Its known that alkali metals have low melting and boiling points but as we give heat to a alkali meta..it readily looses 1electron &becomes stable, thn how it can have low melting point?

Dear Ranjita,

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Consequently, the metallic bonds in these metals are not very strong and their melting and boiling points decrease on moving down the group.
