Question

The reducing power of an element increases down in the group while decreases in a period. Give reason...​

Answer 1

Answer:

The basic fundamental for this question is the size of the Elements

Explanation:

As we know that the size of the elements decrteases along the period and increases down the group the following explanation can be made:

1)Since the size of element increases down the group the valance shell of that element is lesser and lesser attractred by the nucleus.

as the nucleus attracts it lesser the ability of accepting electrons decreases, as this ability decreases the reducing character also decreases (rather we can say oxidising character increases)

2) In same way you can apply your mind in case of period

Answer 2

Answer:

As we move down the group, effective nuclear charge decrease, therefore electron can be easily ejected and reducing power increases. In period effective nuclear charge increases, therefore ejection of electron becomes difficult and reducing power decreases.
