WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.
