The orbital diagram is shown in the image attached.
The orbital diagram of sulfur
The 1s, 2s, 2p, 3s, and 3p orbitals in the orbital diagram are filled with electrons; each orbital can hold a certain number of electrons. Lower energy orbitals are filled before higher energy ones, according to the Aufbau principle.
Based on the distribution of electrons in atomic orbitals, the Pauli exclusion principle and Hund's rule show that the sulfur atom, which has 16 electrons total, has a stable electron arrangement.
