In case of metals that is group 1, 2 and13 as we move down a group the reactivity increases while in case of non metals that is group 14, 15 ,16 and 17 the reactivity decreases
for example in group 1 potassium is more reactive than sodium and lithium
while in group 17 chlorine is more reactive than bromine nad iodine which are below chlorine.
