Because it is so “anxious” to pull another electron into its orbit, chlorine is an extremely reactive element.

Why are halogens so important?

Halogens are among the most reactive of all elements. They have seven valence electrons, so they are very “eager” to gain one electron to have a full outer energy level. Halogens have a variety of important uses, such as preventing tooth decay and killing germs.
