Why chlorine is more reactive than hydrogen

Lynna [10]

Answer:

Hi Todoroki here!!!

Explanation:

Chlorine has the electron configuration [Ne]3s 2 3p 5, with the seven electrons in the third and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell.

Your welcome!!
