The correct order of density of \(\mathrm{Be}, \mathrm{Mg}, \mathrm{Ca}, \mathrm{Sr}\) is
- A \(\mathrm{Sr}\gt\mathrm{Be}\gt\mathrm{Mg}\gt\mathrm{Ca}\)
- B \(\mathrm{Be}\gt\mathrm{Mg}\gt\mathrm{Ca}\gt\mathrm{Sr}\)
- C \(\mathrm{Mg}\gt\mathrm{Ca}\gt\mathrm{Sr}^{\prime}\gt\mathrm{Be}\)
- D \(\mathrm{Ca}\gt\mathrm{Sr}\gt\mathrm{Be}\gt\mathrm{Mg}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Sr}\gt\mathrm{Be}\gt\mathrm{Mg}\gt\mathrm{Ca}\)
Step-by-step Solution
Detailed explanation
Density of Be is higher than Mg an Ca due to small size.
