Oxygen affinity
WebElectron 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. WebFigure 1. When molecular oxygen encounters an isolated heme molecule, it rapidly converts the Fe (II) to Fe (III). The oxidized heme binds oxygen very poorly. Obviously, if this happened to the Fe (II) groups of hemoglobin and …
