Exothermic affinity

This property is used to measure atoms and molecules in the gaseous state only, since in a solid or liquid state their energy levels would be changed by contact with other atoms or molecules. A list of the electron affinities was used by Robert S. Mulliken to develop an electronegativity scale for atoms, equal to the average of the electrons affinity and ionization potential. Other theoretical concepts that use electron affinity include electronic chemical potential and chemical hardness. … WebElectron affinity is exothermic for some elements and endothermic for others. The electron affinity describes the energy needed to remove an electron from a neutral atom. Electron affinity is always negative. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer
