The valence electron configuration for chlorine is s2p5.

Chlorine has an electron configuration of 1s22s22p6,3s23p5.

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 3p5.

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 3s23p5 with seven valence electrons.

I hope this was helpful.
