P3+
P3+
under one method - P has oxidation number of -3, this is where H is assigned +1 except in metal hydrides. Using the electronegativity method and using Pauling EN H is slightly more electronegative than P so on that method P would be +3. It all depends where you are taught.
P = +5 PO4^3- = -3 4(-2) + p = -3 P =5
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.
