Ionization Energy and Electron Affinity - Purdue University

WebApr 5, 2024 · Ans: The answer is the ionization energy is always positive because every solitary electron is bound and therefore, the electron has negative energy. So the … 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.
