The species of phosphorus that have the highest oxidation number are H₃PO₄, P₂O₅, PCl₅.
What is oxidation number?
Oxidation number can be described as the oxidation state, which is the total number of electrons that can be gained or loose by an atom so as to be able to form a chemical bond with another atom.
It should be noted that The species of phosphorus that have the highest oxidation number are H₃PO₄, P₂O₅, PCl₅.
oxidation state which can be as well be described as the oxidation number, serves as the hypothetical charge that is been contained by an atom in a case where all the bonds to different atoms were fully ionic.
This is the degree of oxidation of an atom as regards the chemical compound, hence oxidation state may be positive, negative or zero.
