E O Home - AP Student.. 6 Elk Grové Unifled Constants | Peniodic Table Oxidation states are important for keeping track of electrons in oxidation-reduction reactions. Here are some general rules to remember: Neutral compounds • Atoms of a free element have an oxidation number of 0. • Monoatomic ions have an oxidation state equal to their charge. Polyatomic ions and neutral molecules have a charge equal to the In a neutral compound, the sum of the oxidation states is zero. Note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. In H2O, for example, each hydrogen atom has an oxidation state of +1 and each oxygen atom has an oxidation state of -2 for a total of 2(+1) + (-2) = 0. %3D charge on the species. • Metals in compounds have positive oxidation states. Group 1A and 2A metals have oxidations states of +1 and +2 respectively. • Nonmetals in compounds have oxidation states with the priority listed Part A What is the…
