Draw the orbital diagram for sulfur.

• Ignore the Aufbau principle and Pauli exclusion principle

• Arrange the electrons in the 4s orbital only

• The correct answer for the question is to draw the orbital diagram for sulfur by arranging the electrons in the 1s, 2s, 2p, 3s, 3p, and 3d orbitals according to the Aufbau principle and Pauli exclusion principle.
