how many electrons does an atom need to completely fill the five lowest energy levels?
An atom of neutral bromine possesses 35 electrons. In its ground configuration, how many fundamental energy levels are required to accommodate this number of electrons? That is, what is the smallest value of n needed so that all 35 of bromine's electrons occupy the lowest possible quantum energy states consistent with the Pauli exclusion principle?
A second important result is that electrons will fill the lowest energy states available. This would seem to indicate that every electron in an atom should be in the n=1 state. This is not the case, because of Pauli's exclusion principle. The exclusion principle says that no two electrons can occupy the same state. A state is completely characterized by the four numbers n, l, ml, and ms, where ms is the spin of the electron. An important question is,...
