Valency of Phosphorus in Compounds

In the given compounds, the valency of phosphorus is as follows:

1. Na3PO4: In this compound, phosphorus exhibits a valency of +5. This is because it forms a compound with three sodium atoms, each with a valency of +1, to balance the overall charge of the compound. The phosphate ion (PO4) has a charge of -3, requiring the phosphorus to have a valency of +5 to balance the charges.

2. PH3: In this compound, phosphorus exhibits a valency of -3. Phosphine (PH3) is a colorless, flammable, and toxic gas with a characteristic odor of garlic or rotting fish. It is a lower valency compound of phosphorus, where phosphorus has a valency of -3.

3. K2HPO4: In this compound, phosphorus exhibits a valency of +5. Potassium dihydrogen phosphate (K2HPO4) is a salt formed by the partial neutralization of phosphoric acid. The valency of phosphorus in this compound is +5.

4. P2O5: In this compound, phosphorus exhibits a valency of +5. Phosphorus pentoxide (P2O5) is a chemical compound with the formula P4O10. It contains phosphorus in its highest oxidation state of +5.

These valencies are determined based on the specific chemical properties and bonding characteristics of phosphorus in each compound.
