Question:
The activity of alkaline earth metals as reducing agent
The activity of alkaline earth metals as reducing agent
Show Hint
Lower ionization energy → stronger reducing agent.
Updated On: Apr 23, 2026
- decreases from Be to Ba
- increases from Be to Ba
- increases from Be to Ca and decreases from Ca to Ba
- decreases from Be to Ca and increases from Ca to Ba
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Reducing power depends on ease of electron loss
Step 1: Down the group, atomic size increases.
Step 2: Ionization energy decreases from Be to Ba.
Step 3: Lower ionization energy means easier loss of electrons.
Step 4: Hence reducing power increases down the group.
Conclusion:
Reducing activity increases from Be to Ba
