1. Electron Configuration of Sulfur:
* Sulfur (S) has an atomic number of 16, meaning it has 16 protons and 16 electrons.
* The electron configuration of sulfur is: 1s² 2s² 2p⁶ 3s² 3p⁴
2. Identifying the Third Energy Level:
* The third energy level is indicated by the "3" in the electron configuration.
* It includes the 3s and 3p orbitals.
3. Counting the Electrons:
* The 3s orbital has 2 electrons (3s²).
* The 3p orbital has 4 electrons (3p⁴).
* Total electrons in the third energy level: 2 + 4 = 6 electrons
Therefore, there are 6 electrons in the third energy level of a sulfur atom.
