A) 1s, 2s, 3s, 2p, 3p, and 3d
B) 1s, 2s, 2p, 3s, 3p, and 3d
C) 1s, 2p, 3d, 2s, 3s, and 3p
D) none of these

Question

Quizplus · Accepted Answer

The order of filling orbitals is based on the increasing energy levels of the orbitals. Within a given energy level, orbitals are filled in order of increasing angular momentum (l) values. The correct order of filling orbitals is 1s, 2s, 2p, 3s, 3p, and 3d. Therefore, option B is the correct order.
