Rules for assigning Oxidation States
- 1. Ox state of any element in std state is zero.
- 2. Sum of ox states of atoms in neutral molecule must always be zero, sum of ox states of atoms in an ion must equal the ion's charge.
- 3. Group 1 metals have a +1 ox state, Group 2 metals have a +2 ox state
- 4. F has a -1 ox state
- 5. H has a +1 ox state when bonded to something more electronegative than carbon and a -1 ox state when bonded to an atom less electronegative than carbon, and a zero ox state when bonded to carbon
- 6. Oxygen has a -2 ox state
- 7. The rest of the halogens have a -1 ox state, and the atoms of the oxygen family have a -2 ox state
- --> (A metal will never assume a negative ox state!)
