Question

The difference between the number of shared electrons and unshared electrons in NH3 is a) 4 b)2 c)0 d)3 Please provide a step by step solution. Thanking you in advance

Answer 1

Answer:

NH

3

: 3 bond pairs and one lone pair because, out of 5 valence electrons of nitrogen, only 2 electrons are left to form a lone pair.

H

2

O: 2 bond pairs and two lone pairs because, out of 6 valence electrons of oxygen, 4 electrons are left to form 2 lone pairs.

XeF

2

: 2 bond pairs and three lone pairs because out of 8 valence electrons of xenon, 6 electrons are left to form 3 lone pairs.

So, the ratio of lone pairs is 1:2:3

I hope you can understand my solution
