Question

why is nitrogen a gas while phosphorus is a solid?? ​

Answer 1

Answer:

Due to strong p pie-p pie multiple bonding, nitrogen forms a triple bond with other nitrogen atom giving N2 molecules. Wheras phosphorous does not form p pie-p pie multiple bonding it forms d pie- p pie single bond with other phosphorus atom giving P4 molecules. Thus nitrogen exists as gas and phosphorus as a solid.
