Due to larger atomic size PP is unable to form pi bonds and so it is tetra-atomic in which each PP atom is linked with 3 other PP atoms by 3 sigma bond. But, due to smaller atomic size NN forms 1 sigma and 2 pi bonds i.e. triple bonds with other NN atom and exists as diatomic molecule.

Nitrogen is smaller in size hence it forms multiple bonds with other nitrogen and exists as diatomic molecule. Whereas phosphorus atomic size is more so it can form single bond with other phosphorus atoms. Hence it exists as tetra atomic molecule.
