Step-by-step solution
The density of the alkaline earth metals first decreases down the group and then increases. The variation in the densities is a result of the cumulative effect of the atomic size and various inter molecular forces acting in the metal atoms. The correct order of the density is:- Ca (1.55) < Mg (1.74) < Be (1.84) < Sr (2.63)
