Figure was constructed using the Pauli exclusion principle and indicates that the n = 1 shell holds 2 electrons, the n = 2 shell holds 8 electrons, and the n = 3 shell holds 18 electrons. These numbers can be obtained by adding the numbers given in the figure for the subshells contained within a given shell. How many electrons can be put into the n = 5 shell, which is only partly shown in the figure?
