The electron configuration of sulfur (S), which has an atomic number of 16, is:
**1s² 2s² 2p⁶ 3s² 3p⁴**
This means that sulfur has 2 electrons in the 1s subshell, 2 electrons in the 2s subshell, 6 electrons in the 2p subshell, 2 electrons in the 3s subshell, and 4 electrons in the 3p subshell.
From your options, the correct representation of sulfur's electron configuration is:
**1s² 2s² 2p⁶ 3s² 3p⁴** (which corresponds to the second option: 1s² 2s² 2p⁶ 3s² 3p⁴).
**1s² 2s² 2p⁶ 3s² 3p⁴**
This means that sulfur has 2 electrons in the 1s subshell, 2 electrons in the 2s subshell, 6 electrons in the 2p subshell, 2 electrons in the 3s subshell, and 4 electrons in the 3p subshell.
