Question

Calculate the valency of sodium and silicon mentioning its electronic configuration.

Answer 1

Answer:

atomic number of sodium is 11

so it's electronic Configuration is 2,8,1

K=2

L=8

M=1

so it's valency is +1

atomic number of silicon is 14

so it's electronic configuration is 2,8,4

K=2

L=8

M=4

so the valency of silicon is 4

silicon is a Metalloid so it can act either as a metal or a non metal so it's valency can either be +4 or - 4

but generally the valency of silicon is only 4
