Chem 2 AP Test 1: Things to Memorize The 8 common polyatomic ions: acetate C 2 H 3 O 2 1- (also written as CH 3 COO 1-) ammonium NH 4 1+ carbonate CO 3 2-chlorate ClO 3 1-hydroxide OH 1-nitrate NO 3 1-phosphate PO 4 3-sulfate SO 4 2-Be able to predict properties using the periodic table in terms of number of valence electrons , number of shells(main energy levels) and net nuclear force(kernel charge). Metals in Groups IA, IIA, and IIIA will form ions that have charges of 1+, 2+, and 3+ respectively. These positive ions have only one possible charge and are named by using the name of the element. Metals(or nonmetals) that have several positive oxidation states must indicate the charge of the ion by writing a Roman numeral in parentheses following the name of the element. Negative, monatomic (one atom) ions are named by using the root word of the nonmetal and adding the suffix -ide . Nonmetals in Groups VIIA, VIA, VA and IVA will form ions that have charges of 1-, 2-, 3-, and 4- respectively in binary(two element) compounds. The patterns used to determine –
