Answer:
They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.
Explanation:
any of the elements lithium, sodium, potassium, rubidium, cesium, and francium, occupying Group IA
They are Group one metals in the periodic table.
Are very reactive.
Have low melting and boiling points.
Have 1 valence electron.
Weak metallic bonding therefore soft.
Sodium, Potassium, Rubidium, Caesium, Lithium, Francium
