Vedclass · Answer

(D) The density of alkaline earth metals ($IIA$ group) generally increases down the group as atomic mass increases faster than atomic volume.However,$Mg$ is an exception due to its crystal structure.The densities of the elements are: $Be (1.85 \ g/cm^3)$,$Mg (1.55 \ g/cm^3)$,$Ca (1.55 \ g/cm^3)$,$Sr (2.63 \ g/cm^3)$,$Ba (3.59 \ g/cm^3)$.Comparing the given options,the order $Mg < Be < Ca$ is the most accurate representation of the relative densities among these three elements.
