NettetElectron 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. Nettet14. apr. 2024 · Student evaluations of teaching (SETs) are commonly used to assess the quality of teaching in higher education. They are also incorporated in decisions about hiring and promotion of faculty (Braga et al., 2014; Kreitzer & Sweet-Cushman, 2024).This is the case despite an abundance of research demonstrating that SETs may not—or at least …

NettetElectron Affinity – Oxygen. Electron affinity of Oxygen is 141 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
