What is the order of density among alkaline earth metals?

Density

Alkaline Earth metals are comparatively denser and harder than the alkali metals of group I.

The alkaline Earth metals comparatively smaller atomic size leads to the closely packed crystal lattices resulting in stronger metallic bonds. This characteristic also results in increased hardness and higher density.
