The 1s, 2s and 2p subshells are completely filled (a maximum of two electrons go into the 1s subshell and a maximum of two electrons go into the 2s subshell. The 2p subshell includes 3 orbitals, with 2 electrons maximum per orbital). The 3s subshell has only one of a maximum of two electrons.
1S2 2S2 2P6 3S1
Completely filled?
5 because level 1 has 1 orbital filled, level 2 has 4orbitals filled becuase sublevel s has one, and sublevel p has 3,and the third level has zero. Each orbital can hold 2electons to be filled, and by having orrbital s only hold 1, theorbital is not filled.
