MCQ
The activity of alkaline earth metals as reducing agent :
  • A
    decreases from $Be$ to $Ba$
  • increases from $Be$ to $Ba$
  • C
    increase from $Be$ to $Ca$ and decreases from $Ca$ to $Ba$
  • D
    decreases from $Be$ to $Ca$ and increases from $Ca$ to $Ba$

Answer

Correct option: B.
increases from $Be$ to $Ba$
Alkaline earth metals configuration: $ns^2$
So, they have tendency to loose electron so they are reducing agents.
As we move down, electronegativity decreases so reducing nature increases.
