- Rules for assigning oxidation numbers
- The oxidation number for an
element in its elemental form is 0
- The oxidation number of
a monatomic ion is equal
to the charge on the ion
- The sum of all the oxidation
numbers in a compound is 0
- For polyatomic ions the
sum of all the oxidation
numbers must be equal
to the charge on the ion
- Oxygen has an oxidation number of -2
except when bonded to fluorine when
its +2 and in peroxides when is is -1
- Hydrogen has an oxidation
number of +1 except when bonded
to metals in hydrides when it is -1
