In the Bohr model, ____ electrons fill the first energy level, ____ electrons fill the second energy level, and ___ electrons fill the third energy level.
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.
