MCQ
he most active metal is:
- A$Be$
- B$Ca$
- ✓$Ba$
- D$Mg$
✓
Answer
Correct option: C.
$Ba$
On moving down the group, the electropositive character increases. Hence, the chemical reactivity also increases from $Be$ to $Ba$.
Therefore, the most active metal in alkaline earth metal is barium $(Ba)$.
Therefore, the most active metal in alkaline earth metal is barium $(Ba)$.
