How we can find valency?

1.	How we can find valency?
Answer» If the electron present in the outermost shell are 1,2,3,4 then these numbers are the valency of that particular element if the number of electrons are more than 4 than we have to subtract it from 8 then we will get its valency.For examle:-Clorine - 2 , 8 , 7 Then we have to subtract 7 from 8 than we will get 1 as its valency. By looking at the electrons in outermost shell:) By k l m n shell By k l m n shell
