1. nitrogen because of its small size & high electronegativity forms pâˆ©-pâˆ© multiple bonds. Therefore, it exist as a diatomic molecule having a triple bond bw the 2 N-atoms. Phosphorus , on the other hand , due to its larger size & lower electronegativity usually does not form pâˆ©-pâˆ© multiple bonds with itself.Instead it prefers to form p-p single bonds & hence it exists as tetrahedral P₄ molecules

1.....i think this way

N2=946 KJ PER MOLE
N-N=160 KJ PER MOLE
P-P=215 KJ PER MOLE
P2=845 KJ PER MOLE
GREATER BINDING ENERGY GREATER STABILITY

COMPARE IT
