Sulfur (Z = 16)
A

E
Verified step by step guidance1
Identify the atomic number of sulfur, which is 16. This means sulfur has 16 electrons.
Start filling the electron orbitals following the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level to the highest.
The first two electrons will fill the 1s orbital, giving us 1s^2.
The next two electrons will fill the 2s orbital, resulting in 2s^2.
The next six electrons will fill the 2p orbital, resulting in 2p^6. This accounts for 10 electrons so far. Continue filling the 3s orbital with 2 electrons (3s^2) and the remaining 4 electrons will go into the 3p orbital (3p^4), completing the electron configuration for sulfur.
