Honors Chemistry Review Packet 2016 Name: ________________________________ Section I: Reading the Periodic Table Define the following terms: Period – Group (or Family) – Periodic Function – What do elements in the same group or family have in common with each other? Label the groups by number on the periodic table below, then identify the columns of the families below: Alkali metals Noble Gases Alkaline Earth Metals Transition Metals Halogens Inner-Transition Metals Draw the staircase on the periodic table above. How can you tell whether an element is a metal, a non-metal, or a metalloid based on its location on the periodic table? Atomic Number – Average Atomic Mass – What are valence electrons? Label the number of valence electrons for each column on the periodic table below: Section II: Types of Bonding A cation is a ______________ charged ion that forms when an atom ____________ one or more electrons. An anion is a ______________ charged ion that forms when an atom ____________ one or more electrons. Ionic compounds are held together by ionic bonds formed from the ________________________between positively charged ______________ cations and negatively charged ______________ anions. Because ionic compounds consist of large numbers of ions held together in a lattice structure, they do not exist as individual molecules. Instead, a _________________ indicates the simplest ratio of atoms in an ionic compound. Molecular compounds are held together by ______________ bonds that are formed when electrons are shared between two or more _____________________atoms. The simplest unit of a molecular compound is called a(n) ___________ _____. Label the following compounds as either ionic or molecular: How can you tell? _______________________________________________________ 1. CaF2 6. Cu2O 2. CO2 7. N2O3 3. MgO 8. ClF 4. AlCl3 9. LiCl 5. H2O 10. Ca3N2 What does the octet rule state? Use the octet rule to predict the charges of the s-block and p-block elements on the periodic table below. Different elements can form different types of ions, based on the number of _____________________they have. The charge an element has in a compound is sometimes known as its ____________________. Note that hydrogen forms the hydrogen ion (H+) in compounds with _______________ and the hydride ion (H–) in compounds with ________________. Many elements, including most of the _______________ metals, have oxidation states that are difficult to predict from their location on the periodic table. These elements can often form more than one type of ion. For instance, iron may form a +2 ion or a +3 ion in an ionic compound. Determining Oxidation States Practice Wkst Determine the oxidation number of the underlined element in each example: 1. BrCl 11. NaAuCl4 2. Au2O3 12. K2W4O13 3. KMnO4 13. NbOF63– 4. NaClO4 14.

Na3VO4 Section IV: Nomenclature Practice I Notes: First decide whether to use the Ionic or Covalent naming rules. (If the first element is a metal or a polyatomic ion than follow the rules for Ionic compounds) Next – If covalent then write the subscript on each element as a prefix in front of the elements chemical name Ex: S3 would be written as trisulfur The second element in the compound has its ending changed to –ide (unless on polyatomic list) However – if the compound is Ionic – you need to identify oxidation states on both the cations and anions before you proceed – and you should not use prefixes.
