It summarizes relationships that exist among elements and their compounds. Thus, many individual properties of elements need not be memorized if periodic relationships are known. This module will further broaden your knowledge about the elements. It allows you to explore the modern periodic table in terms of the following periodic properties of the elements: atomic size, ionization energy, metallic character, electronegativity, and electron affinity. After going through this module, you are expected to: 1. Use the periodic table to predict the chemical behavior of an element (S8MT- IIIi-j-12). Specifically, this module will let you recognize the trends in atomic size, ionization energy, metallic character, electronegativity, and electron affinity of elements across the period and down the family. What's In In the previous module, you were able to identify the elements in the modern periodic table arranged in groups and periods; representative and transition elements, metals, metalloids, and non-metals. In this module, we focus on the variations in atomic properties that are useful in predicting the chemical behavior of elements. Activity 1: The Periodic Properties Direction: Use the clues to solve the puzzle. Across 1. ability to attract electrons 4. repeating trends in element properties Down 2. ability to accept electrons 3. adj., the character of an atom to readily lose an electron 5. energy to remove an electron from an atom 1 What's New The periodic properties of elements can be related to human behavior. Below is a short excerpt from the chapter Argon in Primo Levi's book "The Periodic Table". “The little I know about my ancestors presents many similarities to these gases. Not all of them were materially inert, for that was not granted them. On the contrary, they were—or had to be— quite active, in order to earn a living and because of a reigning morality that held that “he who does not work shall not eat.” But there is no doubt that they were inert in their inner spirits, inclined to disinterested speculation, witty discourses, elegant, sophisticated, and gratuitous discussion. It can hardly be by chance that all deeds attributed to them, though quite various, have in common a touch of the static, an attitude of dignified abstention, of voluntary (or accepted) relegation to the margins of the great river of life.” Adopted from: What Element Are You Lesson Plan. https://kenanfellows.org//kfp-cp-sites/cp04/cp04/sites/kfp-cpsites.localhost.com.cp04/files/What%20Element%20are%20You%20Lesson%20Plan.pdf According to Levi, a chemist, and writer, each element had an associative value—its properties symbolizing certain thoughts and activating specific memories. He describes Argon as a rare gas, part of the air we breathe and need to survive but not always noticed or appreciated. In what way does Levi identify with Argon? What does the element symbolize about his Jewish background? The rotations of planets, seasons, high and low tides are periodic processes in our solar system and nature. Ancient astronomers and astrologers used these observations to regulate the activities of individuals or even of nations. Periodicity is an essential part of our life, as evidenced by the beating of the heart and our eating, sleeping, and waking patterns. The elements in the periodic table are arranged in order of increasing atomic number. These elements display several other trends, and we can use the periodic table to predict their chemical, physical, and atomic properties. Activity 2: Connecting circles! Direction: Using graphs A and B, connect all circles by increasing atomic number with a thin straight line. Figure 1.

What about Graph B? _________________________________________________________________ ____________________________________________________ 2. What does the line in Graph A mean? What about the line in Graph B? You may refer to the periodic table for your answer. ____________________________ ____________________________________________________ What is It The periodic law states that when the elements are arranged in order of increasing atomic number, their physical and chemical properties vary periodically. In this module, we will look at the following physical and chemical properties of an atom, namely; atomic size, ionization energy, metallic character, electronegativity, and electron affinity. Periodic trends are specific patterns present in the periodic table that illustrate different aspects of a certain element. The trends provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods and because of the periodic nature of the elements. Atomic Size The atomic radius of a chemical element is the measure of the size of its atoms. The atomic radius is one-half the distance between the nuclei of two atoms (just like a radius is half the diameter of a circle). Thus, based on the atomic radii, the atomic size patterns are observed throughout the periodic table. The following are the general trends in the size of atomic radii: Periodic table showing trends in atomic size Image Source: https://lavelle.chem.ucla.edu/forum/viewtopic. 3 1. Within each period (horizontal row), the atomic radius tends to decrease with the atomic number (nuclear charge). The largest atom in a period is a Group IA atom and the smallest is a Group VIIIA or noble gas atom. 2. Within each group (vertical column), the atomic radius tends to increase with the period number. Ionization Energy Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase. Conceptually, ionization energy is the opposite of electronegativity. The lower this energy is, the more readily the atom becomes a cation. Therefore, the higher this energy is, the more unlikely it is that the atom becomes a cation (kat·ai·aan). Generally, Periodic table showing ionization energy trends elements on the right side of Source: https://chem.libretexts.org/Bookshelves/Inorganic. Chemistry/Modules_and_Websites_(Inorganic_Chemistry) the periodic table have higher /Descriptive_Chemistry/Periodic_Trends_of_Elemental_Properties/Periodic_Trends ionization energy because their outermost level occupied by the electron is nearly filled. Elements on the left side of the periodic table have low ionization energies because of their willingness to lose electrons and become cations. Thus, ionization energy increases from left to right on the periodic table. Metallic Character The metallic character of an element can be defined as how readily an atom can lose an electron. From right to left across a period, the metallic character increases because the attraction between the outermost electron and the atomic nucleus is weaker, enabling it easier to lose electrons. Metallic character increases as you move down a group because the atomic size is increasing. When the atomic size increases, the outer level of an atom occupied by an electron is farther away. The principal energy level of an atom occupied by an electron increases, and average electron density moves farther from the nucleus. The electrons of the valence shell have Periodic table trends in metallic character less attraction to the nucleus and, as a result, can lose electrons more readily. This causes an increase in metallic character. ● Metallic characteristics decrease from left to right across a period. This is caused by the decrease in radius of the atom that allows the outer electrons to ionize more readily 4 ● ● Metallic characteristics increase down a group. Electron shielding causes the atomic radius to increase, so the outer electrons ionize more readily than electrons in smaller atoms. Metallic character relates to the ability to lose electrons, and nonmetallic character relates to the ability to gain electrons. Electronegativity Electronegativity can be understood as a chemical property describing an atom's ability to attract and bind with electrons. In 1934, Robert S. Mulliken, an American physicist, and chemist suggested on theoretical grounds that the electronegativity (X) of an atom be given as half its ionization energy (I.E.) minus electron affinity (E.A.). 𝐼.𝐸. − 𝐸.𝐴. X= 2 Periodic table trends in electronegativity The nature of electronegativity is effectively described thus: the more inclined an atom is to gain electrons, the more likely that atom will pull electrons toward itself. ● From left to right across a period of elements, electronegativity increases. ● From top to bottom down a group, electronegativity decreases. ● Important exceptions to the above rules include the noble gases, lanthanides, and actinides. The noble gases possess a complete valence shell and do not usually attract electrons. The lanthanides and actinides possess more complicated chemistry that does not generally follow any trends. Therefore, noble gases, lanthanides, and actinides do not have electronegativity values. ● As for the transition metals, although they have electronegativity values, there is little variance among them across the period and up and down a group. This is because their metallic properties affect their ability to attract electrons as easily as the other elements. Electron Affinity As the name suggests, electron affinity is the ability of an atom to accept an electron. Unlike electronegativity, electron affinity is a quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The more negative the electron affinity value, the higher an atom's affinity for electrons. Electron affinity generally decreases down a group of elements because each atom is larger than the atom above it. This means that when an atom is getting larger due to an added electron, this makes an electron to be farther away from the atom's nucleus compared with its position in the smaller atom. With a larger distance between the negatively-charged electron and the positively-charged nucleus, the force of attraction is relatively weaker. Therefore, electron affinity decreases. Moving from left to right across a period, atoms become smaller as the forces of attraction 5 become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period. ● ● Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius. Figure 6.

Which atoms have greater electron affinity, those with low ionization energy or those with high ionization energy? Why? 5. Which atoms have the greater electron affinity, metals or non-metals? Why? What I Have Learned Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. The atomic size of a chemical element is a measure of the size of its atoms. Within each period (horizontal row), the atomic size through its radius tends to decrease with increasing atomic number (nuclear charge). The largest atom in a period is a Group IA atom, and the smallest is a noble-gas atom. Within each group (vertical column), the atomic size tends to increase with the period number. Ionization energy is the energy required to remove an electron from a neutral atom in its gaseous phase. Conceptually, ionization energy is the opposite of electronegativity. Ionization energy increases from left to right (across the period) on the periodic table because of increasing attraction between the positive nucleus and negative outermost electron of the atom. On the other hand, as a family is descended, the number of energy levels occupied by the electron of an atom increases because this outweighs the effect of a higher nuclear charge. As the distance of the outer electrons from the nucleus increases, ionization energy decreases. The metallic character of an element can be defined as how readily an atom can lose an electron. From right to left across a period, the metallic character increases because the attraction between the level of an atom occupied by the electron and the nucleus is weaker, enabling an easier loss of electrons. Metallic character increases as you move down a group because the atomic size is increasing. Electronegativity can be understood as a chemical property describing an atom's ability to attract and bind with electrons. It increases from bottom to top in groups and increases from left to the right across periods. Electron affinity is the ability of an atom to accept an electron. Electron affinity increases from left to right within a period and decreases from top to bottom within a group. What I Can Do Activity 4. Supply me!

Why do you think the electronegativity of He, Ne, and Ar is 0? Answer Key Gr8Q3 Module 8 Activity 1. The Periodic Properties Across 1. Electronegativity Across 4. Periodicity Down 2. Affinity Down 3. Metallic Down 5. Ionization Nonmetals. It is because nonmetals will prefer to accept electrons for the attraction between the nucleus and the gained electron is stronger. High ionization energy. It is because when the ability of an atom to accept electron is stronger, then its ability to release an electron is likewise stronger. Activity 2. Connecting circles Answers may vary. The line is crooked (like the saw teeth with sharp edges or amplitude of a speaker) for both the graphs. Both graphs also show a periodic pattern. In Graph A, atomic radius is greater at certain atomic numbers. It shows that as x increases, y sometimes increases and sometimes decreases. With reference to the periodic table, the pattern is indeed periodic showing that atomic radius decreases from right to left and bottom to top. In Graph B, at certain atomic numbers, first ionization energy appears to be higher. With reference to the periodic table, ionization energy increases from left to right and from bottom to top. Smaller atom. It is because when the atom is smaller, the outermost shell is closer to the nucleus, making their attraction stronger as it gains electron. Smaller atom. It is because the smaller the atom is, the closer the outermost shell is; therefore, it has stronger attraction between the positive nucleus and the negative incoming electron. Activity 3.

Pray for all those that hapless have died, For all who have suffered the unmeasur'd pain; For our mothers that bitterly their woes have cried, For widows and orphans, for captives by torture tried And then for thyself that redemption thou mayst gain I die just when I see the dawn break, Through the gloom of night, to herald the day; And if color is lacking my blood thou shalt take, Pour'd out at need for thy dear sake To dye with its crimson the waking ray.

Romulo I am a Filipino–inheritor of a glorious past, hostage to the uncertain future. As such I must prove equal to a two-fold task–the task of meeting my responsibility to the past, and the task of performing my obligation to the future. I sprung from a hardy race, child many generations removed of ancient Malayan pioneers. Across the centuries the memory comes rushing back to me: of brown-skinned men putting out to sea in ships that were as frail as their hearts were stout. Over the sea I see them come, borne upon the billowing wave and the whistling wind, carried upon the mighty swell of hope–hope in the free abundance of new land that was to be their home and their children’s forever. I am a Filipino. In my blood runs the immortal seed of heroes–seed that flowered down the centuries in deeds of courage and defiance. In my veins yet pulses the same hot blood that sent Lapulapu to battle against the first invader of this land, that nerved Lakandula in the combat against the alien foe, that drove Diego Silang and Dagohoy into rebellion against the foreign oppressor. The seed I bear within me is an immortal seed. It is the mark of my manhood, the symbol of dignity as a human being. Like the seeds that were once buried in the tomb of Tutankhamen many thousand years ago, it shall grow and flower and bear fruit again. It is the insignia of my race, and my generation is but a stage in the unending search of my people for freedom and happiness. I am a Filipino, child of the marriage of the East and the West. The East, with its languor and mysticism, its passivity and endurance, was my mother, and my sire was the West that came thundering across the seas with the Cross and Sword and the Machine. I am of the East, an eager participant in its spirit, and in its struggles for liberation from the imperialist yoke. But I also know that the East must awake from its centuried sleep, shake off the lethargy that has bound his limbs, and start moving where destiny awaits. I am a Filipino, and this is my inheritance. What pledge shall I give that I may prove worthy of my inheritance? I shall give the pledge that has come ringing down the corridors of the centuries, and it shall be compounded of the joyous cries of my Malayan forebears when first they saw the contours of this land loom before their eyes, of the battle cries that have resounded in every field of combat from Mactan to Tirad Pass, of the voices of my people when they sing: “I am a Filipino born to freedom, and I shall not rest until freedom shall have been added unto my inheritance—for myself and my children and my children’s children—forever.” 14
