What relationship is there between electronic configuration and period

1.	What relationship is there between electronic configuration and periodic family?What relationship is there between electronic configuration and periodic family?
Answer» Electronic configuration express about the arrangement of ELECTRONS in an atom. So we can calculate the Group no. and Period no.Explanation:Maximum principal NUMBER express about the outer shell which is equal to the period number. If period change means orbit change. For Group no. If last ELECTRON ENTERS in S orbital then the no of electrons in s orbital is the group number If last electron enters into d orbital then group number is equal to the number of electrons added by 2. If last electron enters into p orbital then group number is equal to number of electrons in p orbital added by 12. all F block elements are in 3rd group.
