In all phosphates the oxidation number of phosphorus is +5.
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
Bismuth is in the p block. It shows +3 as the oxidation number.

There are two oxidation numbers. P shows +5 oxidation number.
The oxidation number for the molecule Br2 is 0.
