Question

question):-
the nitrogen has 5 valence electron configuration so why it makes only four bond????....​

Answer 1

Answer:

Recall that covalency is the number of shared electron pairs formed by an atom of that element. Nitrogen's maximum covalency is indeed 4. ... This is also the maximum covalency for the nitrogen atom, since it has no more unpaired electrons that could be paired up with other atoms, to form more covalent bonds.

Answer 2

Answer:

Nitrogen has a lone pair, that accumulates a slight negative charge. When an electron deficient atom approaches Nitrogen, Nitrogen readily gives the lone pair to the electron deficient atom.

Explanation:

Covalency is the number of shared electron pairs formed by an atom of that element. Nitrogen's maximum covalency is 4. This is also the maximum covalency for the nitrogen atom, since it has no more unpaired electrons that could be paired up with other atoms, to form more covalent bonds.
