In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.

How is HPO4 is formed?
That's not a stable compound. If you meant HPO4--, it can be formed by either the reduction of the PO43- ion or oxidation of the H2PO4- ion.
What is the oxidation numbers in PO34?
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
What is the sum of the oxidation numbers for P2O5?
There are two oxidation numbers. P shows +5 oxidation number.
What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well

It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
Can metals have positive and negative oxidation numbers?
No, they can't only have positive oxidation numbers in compounds.
Does oxidation numbers take into account stoicheometery?
The simple answer is not always. The stoicheometry deals with oxidation numbers only in redox reactions. The ratio of the change in oxidation numbers is straightly its stoicheometry.
What is the oxidation number of ZnCl?
The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
What are the oxidation numbers of the elements fe2o3?
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
