Vedclass · Answer

(A) The density of alkaline earth metals ($IIA$ group) generally increases down the group as the atomic mass increases more significantly than the atomic volume. However,there is an anomaly for $Ca$ and $Mg$. The correct order of density for the first three elements is $Ca < Mg < Be$. The complete order for the group is $Ca < Mg < Be < Sr < Ba$.

The correct order of density in the $IIA$ group (alkaline earth metals) is:
