Question

What is the valence electron configuration for chlorine?

Answer 1

The valence electron configuration for chlorine is `s^2 p^5`.

Chlorine has an electron configuration of `1s^2 2s^2 2p^6, 3s^2 3p^5`.

Chlorine is found in the group 17, the halogens on the periodic table.
Chlorine is in the 3rd energy level, (3rd row) and 5th column of the 'p' block `3p^5`.

The valence electrons are always found in the 's' and 'p' orbitals of the highest energy level of the electron configuration making the valence orbitals 3s and 3p and making the valence configuration `3s^2 3p^5` with seven valence electrons.

I hope this was helpful.
