Question

Difine valency by taking the example of silicon and oxygen
​

Answer 1

The electronic configuration of the element is – K=2, L=8,m=4. According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas. Hence, valency of silicon is 4.

Answer 2

The electronic configuration of the element is – K=2, L=8,m=4. According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas. Hence, valency of silicon is 4.
