Question

The valency of nitrogen in NH3


The valency of nitrogen in NH3

Answer 1

3 - valency of nitrogen in NH3

Answer 2

Explanation:

Number of valence electrons means the number of electrons present in the outermost shell.

Hence, the atomic number of nitrogen atom is 7 and its electronic distribution is 2, 5.

Therefore, it means that there are 5 valence electrons present in a nitrogen atom.

Similarly, in a $NH_{3}$ molecule there is presence of one lone pair of electron on nitrogen atom and three hydrogen atoms. So, in total there are 5 electrons.

Thus, we can conclude that the valency of nitrogen in $NH_{3}$ is also 5.
