Question

In group 1 of the periodic table, metals like Francium, Rubidium can easily loose electrons than lithium and sodium. Then why are li and na calledactive and more reactive metals?? rubidium looses electron more easily then why is it not more reactive??

Answer 1

This is not so. The reactivity of group 1 metals increases down the group as Li < Na < K < Rb < Cs < Fr due to decrease in ionization enthalpy.
