1. Electron Configuration:

* Sulfur (S) has an atomic number of 16, meaning it has 16 electrons.

* Its electron configuration is: 1s² 2s² 2p⁶ 3s² 3p⁴

2. Shielding Electrons:

* Shielding electrons are the inner electrons that block the outer electrons from the full attraction of the nucleus.

* In sulfur, the 1s², 2s², and 2p⁶ electrons are all inner electrons.

3. Calculation:

* Add the number of electrons in the inner shells: 2 + 2 + 6 = 10

Therefore, sulfur has 10 shielding electrons.
