5. In the phosphate ion, PO43- O is -2 the overall charge is 3- so P must be +5 ( +5-8=-3)
Pis in the p block. It shows +3 and +5 oxidation numbers.
The oxidation state of P in PO33- is +3. This can be determined by assigning -2 to each oxygen atom and solving for the unknown oxidation state of phosphorus to ensure the overall charge of the ion is balanced.
It is 5.
In H3PO3 each H is 1+ for a total of 3+. Each O is 2- for a total of 6-. So, there is 3+ and 6- giving a net of 3-. In order to make the molecule neutral, P must have an oxidation state of 3+.
The oxidation number of phosphorus (P) in Mn3P2 is -3. This is because the overall charge of the compound is neutral, and manganese (Mn) has an oxidation state of +2. Since there are 2 phosphorus atoms, each must have an oxidation state of -3 to balance the overall charge.

The oxidation state of phosphate (PO4) is -3. This is because oxygen (O) typically has an oxidation state of -2, so there are 4 oxygen atoms in the phosphate molecule, contributing to a total charge of -8. This leaves the phosphorus atom with an oxidation state of +5 to balance the overall charge to -3.
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.
The formula for the compound containing Ga and P is GaP. This is because the oxidation state of Ga is +3, and the oxidation state of P is -3. By combining one atom of Ga with one atom of P, they balance each other out to form a neutral compound.
In Mg2P2O7, magnesium (Mg) has an oxidation state of +2, phosphorus (P) has an oxidation state of +5, and oxygen (O) has an oxidation state of -2. The sum of the oxidation states for each element in the compound must equal zero due to its neutrality.
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
It is 5.
The oxidation number of P in H2PO2- is +1. This is because each hydrogen atom has an oxidation state of +1, and the overall charge of the ion is -1. Therefore, the oxidation number of phosphorus must be +1 to balance out the charge.
