Question

In the third principal energy level,what is the order of energies of the sublevels,from lowest to highest?
A)1s < 2s < 3s
B)3d < 3p < 3s
C)3p < 3s < 3d
D)3p < 3d < 3s
E)3s < 3p < 3d

Quizplus · Accepted Answer

In the third principal energy level, the order of energies of the sublevels from lowest to highest is 3s < 3p < 3d. This follows the general rule that for a given principal energy level n, the s sublevel is lowest in energy, followed by p, then d (if applicable).
