Nitrogen exist diatomic molecule and phosphorus as P_(4). Why ?

Answer»

Solution :DUE to its small size and high ELECTRONEGATIVITY, nitrogen atom forms `ppi-ppi` multiple bonds with itself (triple BOND), so it EXISTS as a discrete diatomic molecule in elemental form, But phosphorus atom has large size and less electronegativity, so it as forms single bond instead of `ppi-ppi` multiple bond. THEREFORE, phosphorus exists as `P_(4)` molecule in its elemental form.
