1. free... | 1. free elements have an oxidation state = 0 ex. Na = 0 and Cl2 = 0 in 2 Na(s) + Cl2(g) |
2. monoatomic... | 2. monoatomic ions have an oxidation state equal to their charge ex. Na = +1 and Cl = -1 in NaCl |
3a. the sum (not polyatomic)... | 3a. the sum of the oxidation states of all the atoms in a compound is 0 |
3b. the sum (polyatomic)... | 3b. the sum of the oxidation states of all the atoms in a polyatomic ion equals the charge of the ion. ex. N = +5 and O = -2 in NO3 -1, (+5) + 3(-2) = -1 |
