Compounds do not have oxidation numbers; only single atoms and elements do.
However:
- hydrogen in compounds always has an ON of +1 (except in hydrides, where it is -1).
- oxygen always has an ON of -2 in compounds (except in peroxides and other certain compounds).
- phosphorous in this case has an ON of +5 (the total ON on oxygens is -8, but -3 is covered by the overall charge of the phosphate anion).

∙ 14y agoH3PO4 is phosphoric acid. It is made up of three hydrogen atoms, one phosphorus atom, and four oxygen atoms.

∙ 6y agoH3PO4 doesn't have a valence, per se. If you refer to combining power or equivalence, then it would be considered to have a valence of 3, but this is not a common nomenclature.

What is the valence number for phosphorus?
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
