WebElectron affinity Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment. WebElectron Affinity – Helium. Electron affinity of Helium is — 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. X + e – → X – + energy ...

WebApr 6, 2024 · 272.4k + views Hint: Electron affinity is the amount of energy released when an electron is added to a neutral gaseous atom in its lowest energy state to form an anion. In the periodic table generally, electron affinity increases moving from left to right, across the period and decreases moving down the group, from top to bottom. WebAug 12, 2024 · The electron affinity (EA) of an element is defined as the energy given of when a neutral atom in the gas phase gains an extra electron to form a negatively …
The electron affinity (Eea) 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 is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Lithium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Lithium. Li + e – → Li – – ∆H = Affinity = 59.6 kJ/mol Electron affinity is one of the most important parameters that guide chemical reactivity.
WebAll noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Their high ionization energy and almost zero electron affinity explain their non-reactivity.
