In assigning formal oxidation states it is necessary to consider the bonding present amongst the species involved. FeS2 was one of the earliest crystal structures solved by X-ray diffraction methods and the simple cubic crystals clearly show sulphur-sulphur bonding within [S-S]2- units. These can be viewed as derived from hydrogen disulphide, H2S2 (cf. hydrogen peroxide, H2O2). Thus FeS2 would be better described as iron persulphide rather than disulphide. In considering the material as Fe2+S22− it is clear that the oxidation state of Fe is +2 while that of each S moeity is -1. A similar problem can be posed via barium peroxide, BaO2, where the oxidation state of barium must be +2 (metal in Gp 2). What is the oxidation state of oxygen in BaO2 ?
oxidation number of I is -1. oxidation number of F is +1.
An element's atomic number gives its number of protons. Checking the periodic table, we see that molybdenum is the element with the atomic number of 42. Thus molybdenum has 42 protons in its nucleus.
Zn has oxidation number +2; S has oxidation number -2
MoS2. -2 for each S, +4 for Mo

MoPO4 is the formula for Molybdenum Phosphate with the Mo in oxidation state III. Mo can have multiple oxidation states. H3PMo12O40 is phosphomolybdic acid - see more information on this species at the related link.

Most molybdenum atoms have 54 neutrons. The atomic number (number of protons) of molybdenum is 42, and its weight (number of protons and neutrons) is around 96. 96 - 42 = 54.
