Question

Why can nitrogen have 4 bonds?

Answer 1

Explanation:

$\huge \pink{answer - }$

Mehrgarh is a Neolithic (7000-3200 BC) site on the Kachi plain of Baluchistan, Pakistan, and one of the earliest sites with evidence of farming (wheat and barley) and herding (cattle, sheep and goats) in south Asia. The site is located on the principal route between what is now Afghanistan and the Indus Valley.

Answer 2

Answer:

If you look at the above image you can see that when nitrogen has a positive charge (one less electron), it can form four covalent bonds. Either with single, double, or triple bonds. It is similar to phosphorus in this regard because they both have five valence electrons (four when they have a positive charge).
