Electron affinity Definition & Meaning - Merriam-Webster

WebOct 28, 2015 · When energy is absorbed from the electron as potential energy, the kinetic energy of the electron is released. You would write a reaction that therefore involves the absorption of an electron into the atom and the release of energy from the electron. 2. S− + e− → S2− + Ee−,2. In contrast, ionization energy is the tendency to give up ... WebThe electron affinity [EA] is the energy change for the process of adding an electron to a gaseous atom to form an anion (negative ion). (3.4.1) X ( g) + e − X − ( g) EA 1. This process can be either endothermic or exothermic, depending on the element. The EA of some of the elements is given in Figure 3.4. 6. Webelectron (an electron outside the semiconductor) which is at rest with respect to the semiconductor. The electron affinity, denoted by (units: eV), of a semiconductor is the energy required to move an electron from the conduction band bottom to the vacuum level and is a material constant.
