The correct answer is: Compounds of unipositive ions of alkali metals are paramagnetic.
Alkali metals are soft and can be cut by knife.
Alkali metals have low density-Lithium, sodium and potassium float on water.
They have low ionization energies and their atoms readily lose the valence electron hence they are most electropositive elements.
Alkali metal salts are diamagnetic.
