Answer:
Electron Affinity
Electron AffinityThe energy released when an electron is added to a neutral gaseous isolated atom to form a negatively charged ion is Electron Affinity.
Explanation:
When electrons are added to an atom, the increased negative charge puts stress on the electrons already there, causing energy to be released. When electrons are removed from an atom, that process requires energy to pull the electron away from the nucleus. Addition of an electron releases energy from the process.
