75 (s) = solid (l) = liquid (g) = gas (aq) = aqueous (dissolved in water) (in parentheses) A couple of other rules of thumb

76 (in parentheses) (II) or (III) = the charge on a metal ion Polyatomic ions can also be in parentheses. Nickel(II) hydroxide = Ni(OH) 2 A couple of other rules of thumb

77 Nonmetals, by themselves, usually form diatomic molecules N 2 O 2 S 2

78 Nonmetals, by themselves, usually form diatomic molecules. N 2 O 2 S 2 So does hydrogen. H 2 A couple of other rules of thumb

79 Metals, by themselves, are usually written as monatomic. Al Cu Na Pb A couple of other rules of thumb

80 When transition metals form ions, they can have different charges. The charge (called the “oxidation state”) is sometimes written in parentheses. Fe(II) Fe(III) A couple of other rules of thumb

81 Major Oxidation States can be found in the appendix on pages 914-916. A couple of other rules of thumb

82 HOMEWORK: Problems 14-20 on pages 285 & 286. When they say “write chemical equations,” they mean balanced equations.
