Nitrogen exists as diatomic molecule and phosphorus as P_4. |
| Answer» Solution :Because of its SMALL size and high electronegativity nitrogen forms `p pi - p pi `multiple bonds. Therefore, it exists as a diatomic molecule having a triple bond between the two N-atoms. PHOSPHORUS, on the other hand, has larger size and LOWER electronegativity and usually does not form `p pi - p pi` multiple bonds with itself. Instead it PREFERS to form P-P SINGLE bonds and hence it exists as tetrahedral, `P_4` molecules. | |
