The vertical columns on the periodic table are called ____________. The horizontal rows on the periodic table are called _____________. Most of the elements in the periodic table are classified as _____________. The elements that touch the zigzag line are classified as _______________. The elements in the far upper right corner are classified as______________. Elements in the first group have one outer shell electron and are extremely reactive. They are called ___________ ______________. Elements in the second group have 2 outer shell electrons and are also very reactive. They are called ______________ ______________ ________________. Elements in groups 3 through 12 have many useful properties and are called _________________ _______________. Elements in group 17 are known as “salt formers”. They are called _________________. Elements in group 18 are very unreactive. They are said to be “inert”. We call these the ______________ ______________. The elements at the bottom of the table were pulled out to keep the table from becoming too long. The first period at the bottom called the _________________. The second period at the bottom of the table is called the _____________________. Mark each of the following at True (T) or False (F): ___1. Properties of the elements are similar across a period. ___2. There are more nonmetallic elements than metallic elements. ___3. Alkaline metals are more reactive than alkali metals. ___4. The atomic number of elements increases across a period and down a group. ___5. Calcium is a member of the alkaline earth family. ___6. Iron belongs to the alkali metal family. ___7. Bromine belongs to the halogen family. ___8. Neon is a noble gas. ___9. An atom of oxygen has a larger atomic radius than an atom of lithium. (Hint: Think about the number of electrons each atom has.) ___10. An atom of sulfur is larger than an atom of oxygen. ___11. An atom of aluminum (Group 13) has five (5) electrons in its outer shell. ___12. Uranium is a transition element. ___13. A chemical family consists of one of the horizontal rows on the periodic table. ___14. Elements within a family will have similar electron structures and will show some similarities in their chemical properties. ___15. Going from left to right in any period, the representative elements show an increasing number of electrons. ___16. The potassium ion is smaller than the potassium atom. (Hint: Think about whether potassium becomes a cation or anion.) ___17. The bromide ion is smaller than the bromine atom. Of the following, which is most similar to calcium? a) K b) Sc c) Mg d) Na Generally, metallic ions are formed by the loss of electrons. a) True b) False What would be the best prediction for the oxidation number of bromine? a) +7 b) -2 c) +1 d) -1 What metal is a liquid at room temperature? a) Br b) Tc c) Hg d) W The elements of the Noble Gas family, except helium, have an outer shell of a) 1 electron b) 2 electrons c) 8 electrons d) 18 electrons The elements which border the zigzag line running diagonally down and to the right end of the table are a) noble gases b) metals c) nonmetals d) metalloids An element with seven electrons in its outer shell would probably have an oxidation number of a) +1 b) +7 c) -1 d) -7 Group--?--of the Periodic Table contains the most active metals. a) 1 b) 3 c) 17 d) 16 The elements located between Group 2 and 13 are called a) triads b) actinides c) lathanides d) transition Fill in the Blank actinide series metal period atomic radii metalloid group nobel gas periodic table lathanide series nonmetal octet rule cation anion As one looks across the periodic table, the___?__decreases as you move from left to right in each period. A(n)--?--has the most stable atoms The element in a(n)--?--are all in the same vertical column. A(n)--?--is an element with both metallic and nonmetallic properties. The elements in a(n)--?--are all in the same horizontal line. The--?--states that an atom with eight electrons in its outer level is particularly stable A(n) --?—is a positively charged ion. Alkali metals form this type of ion. A(n) --?—is a negatively charged ion. Halogens form this type of ion. The --?—and --?—are rare Earth metals.
