How we will find the valency of any element ?
Valency of element is the no. of electron participating in chemical combination. Actually it is the valence shell which is involved in chemical combination.
Therefore if electron present in valence shell is less than 3 than valency is directly equal to number of electron in valence shell.
If electrons present in valence shell are greater than three than 8- no. of valence electrons.To find electrons in valence shell one should know atomic number.
For eg for Al electronic configuration is 2,8,3 as atomic number is 13. Thus valency is 3 as valence shell electron equals to three. N electronic configuration 2,8,5 valency = 8-5 = 3.
