There seems to be a typo in the element symbol. You are likely asking for the electron configuration of Cl, which stands for Chlorine.

Here is the electron configuration of Chlorine (Cl):

1s² 2s² 2p⁶ 3s² 3p⁵

Explanation:

* 1s²: The first energy level (n=1) has 2 electrons in the 's' subshell.

* 2s²: The second energy level (n=2) has 2 electrons in the 's' subshell.

* 2p⁶: The second energy level (n=2) has 6 electrons in the 'p' subshell.

* 3s²: The third energy level (n=3) has 2 electrons in the 's' subshell.

* 3p⁵: The third energy level (n=3) has 5 electrons in the 'p' subshell.

Let me know if you have any other questions about electron configurations.
