What Is The Valency Of Chlorine?

The valency of chlorine refers to electrons present in the outermost shell of an atom. The atomic number of chlorine is 17.

• The atomic number of chlorine is 17.
• The electrical configuration of chlorine is [Ne]3s23p5.
• This indicates that the outermost shell of chlorine has seven valence electrons.
• If there are four or more valence electrons, the valency can be determined as follows: Valency = Valence electron -8. As a result, chlorine has a valency of 8-7, which is 1.
