The alkaline earth metal with lowest density is
- A \(\mathrm{Be}\)
- B \(\mathrm{Mg}\)
- C \(\mathrm{Ca}\)
- D \(\mathrm{Sr}^{\prime}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Ca}\)
Step-by-step Solution
Detailed explanation
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.
