chlorine is a group seven element with outmost energy level lacking only one electron, thus is not stable. when it gains this electron, it gets an octet electron structure(8 e in the vallency shell) this makes it very stable in the enviroment; the reason why chlorine molecule exists due to its stable atoms but chlorine atom does not exist in nature
