1s² 2s² 2p⁶ 3s² 3p⁴
Here's a breakdown:
* 1s²: The first energy level (n=1) has one subshell, the 's' subshell, which can hold up to 2 electrons.
* 2s²: The second energy level (n=2) also has an 's' subshell with 2 electrons.
* 2p⁶: The second energy level also has a 'p' subshell, which can hold up to 6 electrons.
* 3s²: The third energy level (n=3) has an 's' subshell with 2 electrons.
* 3p⁴: The third energy level also has a 'p' subshell with 4 electrons.
This configuration shows the distribution of sulfur's 16 electrons across its different energy levels and subshells.
