the answer is 2, my chemistry proffessor told me so. take it or leave it.
The oxidation number of Fe in Fe2 is +2. Iron typically forms ions with a +2 oxidation state.
The oxidation number of any monoatomic ion is equal to the charge of the ion. For example, the oxidation number of the sodium ion (Na+) is +1, and the oxidation number of the chloride ion (Cl-) is -1.
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.
The oxidation number of H+ is +1. This is because hydrogen typically has an oxidation number of +1 when it forms an ion by losing its single electron.
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-

Iron has 2 oxidation states: Fe2+ and Fe3+ .
The formula for ferric ion is Fe3+. It is the ion form of iron when it has lost three electrons.
The oxidation number of H+ is +1. This is because hydrogen typically has an oxidation number of +1 when it forms an ion by losing its single electron.
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-
The name of the ionic compound Fe2+ is iron(II) or ferrous ion.
+6, because the oxidation number of oxygen is -2x3=-6
manganese is a 3d element. +2 is the oxidation number in this ion.
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
The oxidation number of each hydrogen (H) in H3O+ is +1. The oxidation number of oxygen (O) is -2. Overall, the oxidation number of the H3O+ ion is +1.
