Question

State True or False.

In group IA of alkali metals, the ionisation potential decreases down the group. Therefore, lithium is a poorer reducing agent in gaseous medium.

• A. True
• B. False

Answer 1

The correct option is A True

Reducing agent: an element which can donate electron easily is called reducing agent (which can cause the reduction).
In group IA of alkali metals, the ionization potential decreases(due to increase in size less energies are required to remove the electron) down the group. Therefore, lithium is a poorer reducing agent in a gaseous medium.
So the given statement is true.
Hence statement is true.
