There are two oxidation numbers. P shows +5 oxidation number.
The oxidation number of P in P2O5 is +5. This is because oxygen typically has an oxidation number of -2, and there are 5 oxygen atoms in P2O5. The sum of the oxidation numbers in a neutral compound must equal zero, so the oxidation number of P is calculated as +5.
The sum of oxidation numbers in a neutral compound is always zero, as the charges balance out. In polyatomic ions, the sum of oxidation numbers equals the charge of the ion. When determining oxidation numbers, rules such as assigning elements in their elemental state an oxidation number of zero and hydrogen an oxidation number of +1 are typically followed.
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
The oxidation number of each phosphorus atom in P2O5 is +5. This is because oxygen is assigned an oxidation number of -2 in most compounds, and the overall charge of P2O5 is 0. Since there are two phosphorus atoms, each must have an oxidation number of +5 to balance the -10 oxidation contributed by the five oxygen atoms.
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.

The correct chemical formula should be P2O5 or P4O10 (its dimer) and not P3O10 (as originally asked in the question). The oxidation numbers are -2 for each O +5 for each P
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.

In a neutral compound, the sum of the oxidation numbers of the atoms in the compound is zero.
Zero
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.
The sum of the oxidation numbers in a compound is zero for a neutral compound. This is because the total positive oxidation numbers from the cations must equal the total negative oxidation numbers from the anions to balance out and form a neutral compound.
The oxidation number of P2O5 is Phisphorus +5, Oxygen -2.
The sum of the oxidation numbers in the phosphate ion (PO4^3-) is -3. Each oxygen atom has an oxidation number of -2, totaling -8. The oxidation number for phosphorus is +5 to offset the oxygen atoms and give a total charge of -3 for the ion.
The oxidation state of P in P2O5 is +5. Each oxygen has an oxidation state of -2, so the two oxygens in P2O5 contribute -10 overall. This means the two phosphorus atoms must have a total oxidation state of +10 for the compound to be electrically neutral.
