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 $(Ba)$.
