Electron Affinity - Chemistry LibreTexts
WebThe electron affinity of hydrogen is not the same as the enthalpy change when we add an electron to a hydrogen atom. The electron affinity is the release of the energy, the amount of energy coming out, while the enthalpy change is the change in energy of the system. If the electron affinity, 𝐸 e a, is positive, the enthalpy change for 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. Created by Jay. WebThis page explores the trends in some atomic and physical properties of the Group 7 elements (the halogens) – fluorine, chlorine, bromine and iodine.
