Sir why the metals of group 1, having greater atomic size are soft metals shouldnt they have increased van der waals forces resulting in hard metals Sir why the metals of group 1, having greater atomic size are soft metals shouldnt they have increased van der waals forces resulting in hard metals
First of all metals form metallic bonds.The size of metals of group1 are larger in size.Therefore the distance between the nuclei of the atoms in metallic bond are farther as compared to other metals.Also as the size increases down the group softness too increases.Hope that helps.
