HEY BUDDY HERE IS UR ANSWER !!!
》The halogens in Group 7 of the Periodic Table are the most reactive group of non-metals.
》 They get less reactive as we go down the group (so fluorine is the most reactive halogen).
》 In reactions with metals the halogen atoms gain an electron to form ions with a 1− charge.
