Question

For a neutral atom, the first ionization energy is equal to its electron affinity.

• A. True
• B. False

Answer 1

The correct option is B False

First ionization energy of an element is the energy needed to remove the outermost or highest energy electron from a neutral atom in the gas phase.

Electron affinity is the energy released when an electron is added to a gaseous atom. Unlike ionization energies, which are always positive for a neutral atom, electron affinities can be negative, positive or zero. So they are not equal.
