WebApr 6, 2024 · Electron Gain Enthalpy. KJ mol-1. F-333. Cl-348. Br-324. I-295. The energy released when an electron is added to an isolated gaseous atom is known as electron gain enthalpy. Halogens have negative electron gain enthalpy. However, on moving down the group the electron gain enthalpy turns out to be less negative. WebThe electron affinity (E ea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion.. X(g) + e − → X − (g) + energy. This differs by sign from the energy change of electron capture ionization. The electron affinity is positive when energy is released …
