The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.
The oxidation number of Na in NaCl is +1, while the oxidation number of Cl in NaCl is -1.
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.

There are 3 elements. This is meta phosphoric acid.
The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.
The oxidation number is located in the top right-hand corner of each element box; for many elements there is more than one.
