Question

Put the following energy sublevels in order from least to greatest energy.
A. 1s, 2s, 3s, 4s, 2p, 3p, 4p, 3d, 4d, 4f
B. 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f
C. 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f
D. None of these

Answer 1

The correct order is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f. The correct option is B.

Order of energy sublevels

The correct order of energy sublevel is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

Thus, with the exclusion of 5s, 5p, 6s, 5d, 6p, 7s, 5f, 6d, and 7p, what we have left in order of increasing energy is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f.

Answer 2

The correct order from least to greatest energy for the energy sublevels is;  1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f (Option B).

What is the Aufbau principle?

The Aufbau principle offers a method in which the energy levels in an atoms are arranged from the least to the greatest. We know that electrons are filled into orbitals in order of increasing energy.

Thus, the correct order from least to greatest energy for the energy sublevels is;  1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f (Option B).
