The element that has four total electrons in its outer P orbitals is
Sulphur (s) (answer D)
Sulphur is in group 16 and period 3 in the periodic table therefore Sulphur is in atomic number 16.
Sulphur (S) electronic configuration is 1S2 2S2 2P6 3S2 3P4 or [Ne] 3S2 3P4 therefore the 3P4 subshell of sulphur has only 4 electrons.
