Question

Nitrogen forms N2 but phosphorus forms P4 at room temerature
Why?

Ramya · Accepted Answer

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