Question

Number of electrons in the valence orbit of nitrogen in an ammonia molecule is

• A. 8
• B. 5
• C. 6
• D. 7

Answer 1

The correct option is A 8

Count total electron in valence shell of nitrogen and hydrogen.
of nitrogen and hydrogen.
$\begin{array}{c}H\times \bullet \underset{\bullet }{\stackrel{\bullet \bullet }{N}}\bullet \times H\\ \stackrel{\times }{H}\end{array}$
$\therefore$ Total electrons in $N{H}_3=5+1+1+1=8$
