Question

Quizplus · Accepted Answer

The electron configuration of an atom tells us how many electrons are in each energy level and sublevel. It does not describe the shape of energy levels, the number of isotopes, or the diagram of the atomic nucleus. While the electron configuration does provide information about the maximum number of electrons each energy level can hold, this is not its primary purpose.
