the reactivity of metals changes while going down a group because their valence shell get filled as we go down
so the capability of gaining or losing atoms decreases
thus the reactivity decreases

it means that hydrogen have one ring
it has less radius
and sodium have two rings
it has more radius
but their atoms are same
of same size
infact all atoms in world are of same size
Oh thanks
