Why is energy absorbed when electron is accepted?

Question

Why is energy absorbed when electron is accepted? (Electron Affinity)	Why is energy released when electron is removed? (Ionisation Potential?)And why is it necessary to take an isolated gaseous atom of the element for determining electron affinity and ionisation potential?

Karthikk Kumaresan · Accepted Answer

The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the 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.
