Electron affinity

{
  "id": "MLC-T-CHM-003705",
  "term": "Electron affinity",
  "field": "Chemistry",
  "definition": "The energy change that occurs when an electron is added to a neutral atom or molecule in its gaseous phase to create a negative ion. A positive electron affinity indicates that energy is released during this process, signifying a stable anion formation. This property is typically expressed in units of kilojoules per mole (kJ/mol) or electronvolts (eV) per atom.",
