Question
The reducing power of elements increases down the group but reverse is true for elements along the period, why?
✓

Answer

Reducing power depends upon tendency to lose electrons. It increases down the group, therefore reducing power increases.
Tendency to lose electrons decreases along a period, therefore, reducing power decreases.
