Ionisation energy decreases down the gr...

Ionisation energy decreases down the group in periodic table. Give reason .

Text Solution

Verified by Experts

Down the group, atomic size increases and hence the valence electrons are loosely bound. They require relatively less energy for the removal . Thus ionisation energy decreases down the group in periodic table.
