How many electrons can occupy the second electron shell?

Explanation:
Electrons fill shells with a maximum capacity given by 2n^2, where n is the shell number. For the second shell, n = 2, so it can hold 2 × (2)^2 = 8 electrons. This shell has two subshells, 2s and 2p: 2 in the 2s subshell and 6 in the 2p subshell, totaling 8. The other numbers correspond to different shells or partial subshells, not the full second shell. So the second shell can accommodate eight electrons.
