Vedclass · Answer

(A) The density of alkaline earth metals generally increases down the group as the atomic mass increases more significantly than the atomic volume.However,there is an anomaly in the case of $Mg$ and $Ca$.The densities of the elements are: $Be$ $(1.85 \ g/cm^3)$,$Mg$ $(1.74 \ g/cm^3)$,$Ca$ $(1.55 \ g/cm^3)$,and $Sr$ $(2.63 \ g/cm^3)$.Comparing these values,the correct order is $Sr > Be > Mg > Ca$.

The correct order of density of $Be$,$Mg$,$Ca$,$Sr$ is
