Oxygen forms a -2 ion.
x0 - x= +2.
The compound overall needs to be neutral, so you add up all the charges from the oxygen and add whatever you need to make it neutral.
eg:
FeO - oxidation state of iron = +2, since oxygen forms -2 and compound is overall neutral.
Fe2O3 - -6 from the oxygen. So you need to add +3, and there are two Fe's so you divide it by two - therefore iron is +3.
Hope that helps.

What element forms acidic oxides?
non metals
What element has -1 as an oxidation number?
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
What element forms a gaseous oxide?
Nitrogen forms gaseous oxides. NO,NO2,N2O,N2O3 are few examples.
What is the oxidation number of P?
Phosphorous, or P, has a zero oxidation number in the element. Common oxidation numbers are:- It has a -3 in phosphides, where it forms the P3- ion It has a +3 in oxidation number in for example P4O6, and PCl3 It has a +5 oxidation number in for example P4O10 and PCl5
