the answer is 2, my chemistry proffessor told me so. take it or leave it.
-2
+2 in Fe2+
+2 for Fe2+ ion
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
Oxidation number is +2 for Zn+2 ion
The oxidation number of monoatomic ions is the same as their ion charge: +2 in Fe(II) for Fe2+, +3 in Fe(III) for Fe3+, -2 in sulfide S2-
+1 for H+ ion
+2 for Fe2+ ion
Iron has 2 oxidation states: Fe2+ and Fe3+ .

The oxidation number is a measure of the charge an atom would have if all its bonds were 100% ionic. It can be positive, negative or zero.
Oxidation number is plus two. It is common to every ion of Ca.
+3 for Cr3+ ion
manganese is a 3d element. +2 is the oxidation number in this ion.
No. Fluorine has only two oxidation states. 0 in F2 and -1 in fluoride ion
