Vedclass · Answer

(D) The atomic size of alkali metals increases as we move down the group from $Li$ to $Cs$.As the atomic size increases,the strength of metallic bonding decreases because the valence electrons are further from the nucleus.Consequently,the melting point decreases down the group.Among the given options,$Cs$ (Cesium) is the largest atom and therefore has the lowest melting point.

Which of the alkali metals has the lowest melting point?
