In old nomenclature, oxides of elements were called "earths". The oxides of Group II form alkaline (basic pH) solutions in water; i.e. they are base anhydrides. Thus they were referred to as the alkaline earth metals.

Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
Why is beryllium the least reactive?
Compared to what? But it would be less reactive because the s orbital is filled, the electrons are all paired. If you mean "Why is beryllium the least reactive of the Group II alkaline earth metals?", then this is because it has the least electron shielding, having an electron configuration of 2, 2. Beryllium is at the top as the first of the Group II alkaline earth metals, and reactivity increases as you go down Groups I and II.
