nitrogen has tendency to form multiple bonds with itself. so it exists as a ''discrete'' molecule. whereas phosphorus, and other group members being bigger donot form stable multiple bonds with themselves and hence exist as a solid form.
this the reason for nitrogen existing as a gaseous molecule and phosphorus as a solid.

As Nitrogen pairs up,into N2 molecule which has very strong triple bond there is relatively little attraction between one nitrogen molecule and another, so they move indipendently and form gas.
In phosphorus, the atom do not pair up,they bond to there neighbouring atoms, thus forming a network of bonding holds the atoms together into a solid.

In case of phosphorus four atoms are associated so it have high molecular mass ,large magnitude of venderwall forces so phosphorus is solid and nitrogen is gas.

- N2 is exist as diatomic molecule in which two nitrogen atoms are attached to each other by triple bond this triple bond is due to p(pie)-p(pie) multiple bonding (sidewise overlapping) and such bonding is not possible in phosphorus due to it's large size but possible in nitrogen due to it's small size.

- Nitrogen exists as diatomic molecule. Because of its small size and less no. Of electrons, van der walls force of attractions between N2 molecules is less so it exists as gas. But phosphorus exists as P4. Its size is big and has more mass as well as more no. Of electrons as compared to N2. So it exists as solid.
