Vedclass · Answer

(C) The reactivity of alkali metals with water increases down the group.This is because the ionization potential $(I.P.)$ decreases as we move down the group from $Li$ to $Cs$.Lower $I.P.$ means the valence electron is more loosely held and can be easily lost to form the $M^+$ ion.Since sodium $(Na)$ has a lower $I.P.$ than lithium $(Li)$,it loses its electron more easily,making it more reactive towards water.

As compared to lithium,sodium reacts more quickly with water because:
