The electron affinities of atoms are … WebElectron affinity is defined as The amount of energy released when an electron is added to a neutral atom to form an anion. The electron affinity is the potential energy change of the atom when an electron is added to …
WebElectron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable. Created by Jay. WebTherefore, the electron affinity of TiO 2 was set in the range of 4.1–4.5 eV in this study, and the simulation results are shown in Figure 4. It can be seen from Figure 4a that, with a gradual increase in the electron affinity of TiO 2, V oc shows a gradual downward trend, but the short-circuit current density (J sc) changes slightly.
