Question

Ionization Energy Decreases On Moving Down The Group (True/False)

• A. True
• B. False

Answer 1

The correct option is A True

True. The given statement is true.

Ionization energy

• Ionization energy is the minimum amount of energy required to remove the loosely bounded electron from an atom.
• On moving from left to right in the periodic table ionization energy increases as the nuclear charge increases.
• On moving down the group in the periodic table, the force of attraction between electrons and nucleus decreases.

Therefore, Ionization energy decreases on moving down the group.
