Q. Which of the following sets of quantum numbers represents the highest energy of an atom?

A.            n = 3, l = 0, m = 0, s = + 12

B.            n = 3, l = 1, m = 1, s = + 12

C.            n = 3, l = 2, m = 1, s = + 12

D.            n = 4, l = 0, m = 0, s = + 12

Answer: n = 3, l = 2, m = 1, s = + 12
