InterviewSolution

1.	Write the group and period numbers of oxygen from its electronic configuration (O = 8 = 2, 6).
Answer» Solution :From the electronic configuration of OXYGEN (O = 8 = 2, 6), we find that there are six electrons in its OUTERMOST shell (second shell). Since oxygen is a nonmetal, its group NUMBER = 6 + 10 = 16. Thus, oxygen belongs to group 16 and period 2.
