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. Orbitals:
* Each electron shell has a specific number of orbitals:
* 1s: 1 orbital
* 2s: 1 orbital
* 2p: 3 orbitals
* 3s: 1 orbital
* 3p: 3 orbitals
3. Filled Orbitals:
* Count the number of orbitals that are completely filled with electrons:
* 1s² (filled)
* 2s² (filled)
* 2p⁶ (filled)
* 3s² (filled)
* 3p⁴ (not completely filled, but two of the three orbitals are filled)
Therefore, there are a total of 9 filled orbitals in a sulfur atom.
