The alkaline earth metal with lowest density is

The alkaline earth metal with lowest density is
  1. $\mathrm{Be}$
  2. $\mathrm{Mg}$
  3. $\mathrm{Ca}$
  4. $\mathrm{Sr}^{\prime}$

Solution

The density of alkaline earth metals varies in the following order:- $ \mathrm{Ca} < \mathrm{Mg} < \mathrm{Be} < \mathrm{Sr} < \mathrm{Ba} < \mathrm{Ra} $ This is due to low mass and high volume of $\mathrm{Ca}$ compared to other members
