Rb electronegativity value

WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Krypton in the gas phase, for example, gives off energy when it gains an electron to form an ion of Krypton. Kr + e – → Kr – – ∆H = Affinity = — kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity. 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 on …
