Question

Why energy is released in electron affinity ?​

Answer 1

Answer:

Well,

Explanation:

Energy released in electron

• The energy change that occurs when a neutral atom gains an electron is called its electron affinity.
• When an electron is added to a metal element, energy is needed to gain that electron (endothermic reaction)

An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy.
