Answers

Answered by shraddha2332

Explanation:

Chlorine is in group VII, the halogens - these elements are highly reactive. They have seven electrons in their valence shell so react readily with metals that will give up electrons to form an ionic bond. ... It is this ability to bind to other elements that make chlorine such a good disinfectant.
