Expert Answer:

Group by rules;     if the element is of s - block = group = no of valence electrons.

                               if the element is of p- block = group = 10+no of valence electrons

                                   if the element is of d- block = group = 2+no of(n-1)d electrons

Period = value of n (principal Q no/)
