Question:
The correct order of density of Be, Mg, Ca, Sr is:
The correct order of density of Be, Mg, Ca, Sr is:
Show Hint
In Group 2, density generally increases down the group, except for Beryllium, which has a higher density than Magnesium.
Updated On: Jun 5, 2025
- \( Sr>Be>Mg>Ca \)
- \( Sr>Ca>Mg>Be \)
- \( Be>Mg>Ca>Sr \)
- \( Be>Mg>Sr>Ca \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Density Trend in Alkaline Earth Metals
Density in Group 2 (Alkaline Earth Metals) typically increases down the group, but Beryllium is an exception due to its compact atomic structure.
Step 2: Density Values
Measured densities (g/cm³):
\[
\text{Be} = 1.85, \text{Mg} = 1.74, \text{Ca} = 1.55, \text{Sr} = 2.64
\]
Conclusion
Thus, the correct order is:
\[
Sr>Ca>Mg>Be
\]
