It is very easy...all u have to do is...take an example...
like... 2,8,7
k,l,m
to find the group no...add 10 to the Valence shell...that is,7+10
=17 is the group no.
take another example...
like......2,8,8,2
k,l,m,n
then group no if this will be...4.. because K,l,m,n=are 4 alphabets....
hope it helps uh... brother
