There are 6 of them, so it is not unique. "Unique" means that there is only one.
The alkali metals have a low electronegativity and they easily loss an electron.
Alkali metals are very reactive metals.
Alkali metals are the most reactive metals.

No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
Alkali metals are very reactive metals.
They don't
Alkali earth metals are named after their oxides, alkaline earth.
alkali metals
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
Alkali metals are the metals in family/group I.Lithium, sodium, potassium, Rubidium, Cesium, Francium are Alkali metals.
Alkali metals are very reactive, not dense or hard metals, monovalent, with low electronegativities, with low melting and boiling points, react violently with water, form strong bases, etc.
