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
When considering trends in the periodic table, remember that exceptions can occur due to changes in atomic structure and electron configuration that affect physical properties like density.

- \( {Sr}>{Be}>{Mg}>{Ca} \)
- \( {Be}>{Mg}>{Ca}>{Sr} \)
- \( {Mg}>{Ca}>{Sr}>{Be} \)
- \( {Ca}>{Sr}>{Be}>{Mg} \)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
- The density of the elements typically increases with increasing atomic mass as you go down a group in the periodic table.
- For the alkaline earth metals (Group 2), this general trend applies except for some anomalies due to atomic packing and atomic weight.
- Strontium (Sr) has the highest density among the given elements, followed by beryllium (Be), magnesium (Mg), and calcium (Ca).
