Question

In the Bohr model, ____ electrons fill the first energy level, ____ electrons fill the second energy level, and ___ electrons fill the third energy level.
A) 1, 2, 3
B) 2, 8, 8
C) 8, 8, 8
D) 2, 8, 18

Answer 1

The answer is d Thus, the first energy level holds 2 * 1^2 = 2 electrons, while the second holds 2 * 2^2 = 8 electrons. Each orbital. The third energy level can hold up to 18 electrons, meaning that it is not full when it has only electrons.
