Davisson and Garmer
Heisenberg
4d, 5p, 5f and 6p orbitals are arranged in the order of decreasing energy. The correct option is:
6p > 5f > 5p > 4d
6p > 5f > 4d > 5p
5f > 6p > 4d > 5p
5f > 6p > 5p > 4d
D.
5f > 6p > 5p > 4d
(n + l) values for, 4d = 4 + 2 = 6
5p = 5 + 1 = 6
5f = 5 + 3 = 8
6p = 6 + 1 = 7
Correct order of energy would be
5f > 6p > 5p > 4d
