Question

Why the valency of nitrogen is 3​

Answer 1

Explanation:

The nitrogen atom has 5 electrons in the outermost shell, so it can accept 3electrons to fulfil the octet structure. Therefore the valency of nitrogen in NH3 is 3.

Answer 2

Answer:

this is the answer hope it helps you and plsss mark me as brainliest

Explanation:

valency is calculated

1. if valence electrons ≥ 4 then valency=valence electrons
2. if valence electrons<4 then, 8-valence electrons

Now, valence electrons of nitrogen are 5

as 5>4 so valency of nitrogen=8-5

valency of nitrogen=3
