Answer» Chemicalreactivityincreaseswith INCREASES in atomicnumberdown thegroup in BOTHTHE alkalimetalsand haloges In alkalimetals the reactivity increasesbut inthe HALOGENS itdecreaseswith INCREASESIN atomicnumberdown thegroup . Thereactivitydecreases in thealkalimetalsbut increasesin the halogens withincreasesin atomicnumber . Inboth thealkalimetalsand thehalogensthe chemicalreactivitydecreaseswithincreasesin atomicnumber down thegroup. Answer :B
