How many nonbonding electrons are on each nitrogen atom
A 0
B 2
C 4
D 6

The number of valence electron in the outermost shell of a nitrogen atom is a pair of electrons. Hence, the number of non - bonding electrons on a nitrogen atom is 2.

Therefore, there are two non - bonding atoms.

In ammonia (NH3) the number of non-bonded electrons are 2.

In nitrogen atom there are five electrons in its outermost shell. In ammonia (NH3) three electrons of nitrogen atom covalently bonded with three hydrogen atoms whereas the remaining two are non-bonded electrons.

Due to this non-bonded electron pair, ammonia reacts violently with oxidizing gases such as chlorine, bromine, and other halogens etc so we can conclude that 2 electrons are present in the compound of ammonia.
