Which of the following statements is incorrect? a. The set of quantum numbers n = 4, l = 3, ml = –1, ms = 0 is not permitted because ms = 0. b. The set of quantum numbers n = 3, l = 2, ml = 3, ms = is not permitted because ml exceeds l. c. The set of quantum numbers n = 3, l = 2, ml = 1, ms = is permitted. d. The set of quantum numbers n = 2, l = 2, ml = 1, ms = is not permitted because n = l. e. The set of quantum numbers n = 3, l = 2, ml = 0, ms = is not permitted because ml = 0.

Answer #1

n = 4, l = 3, ml = –1, ms = 0 is not permitted because ms = 0. ----------------true

b. The set of quantum numbers n = 3, l = 2, ml = 3, ms = is not permitted because ml exceeds l.correct

c. The set of quantum numbers n = 3, l = 2, ml = 1, ms = is permitted. ------- correct

d. The set of quantum numbers n = 2, l = 2, ml = 1, ms = is not permitted because n = l.----- correct

e. The set of quantum numbers n = 3, l = 2, ml = 0, ms = is not permitted because ml = 0.-------------incorrect

because if n=3 ,l=2 means

                          3d-orbital that means it has ml values n       -2,-1,0,1,2
