The electron affinity is the potential energy change of the atom when an electron is added to a neutral gaseous atom to form a negative ion. So the more negative the electron affinity the more favourable the electron addition process is.
Electron affinity is the energy produced when a gaseous neutral atom absorbs an electron and becomes a negatively charged ion. When the initial electron is added to an atom, a monovalent anion is released, releasing energy.
The electron affinity ( Eea) of an atom or molecule is defined as the amount of energy release 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. [1] .
4 days ago · Electron affinity is defined as the quantitative measurement of the energy change that results from adding a new electron to a neutral atom or molecule in the gaseous state.
Jan 30, 2023 · Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
Mar 2, 2019 · Electron affinity is the amount of energy required to detach one electron from a negatively charged ion of an atom or molecule. It is indicated using the symbol Ea and is usually expressed in units of kJ/mol. Electron affinity follows a trend on the periodic table.
Chemists define electron affinity as the change in energy, measured in units of kJ/mole, experienced when an electron is added to a gaseous atom. This process creates a negative ion.
The electron affinity ( EA) of an element is the energy change that occurs when an electron is added to a gaseous atom to give an anion. In general, elements with the most negative electron affinities (the highest affinity for an added electron) are those with the smallest size and highest ionization energies and are located in the upper right ...
Definition: Electron Affinity defined as removal of an electron. Electron affinity can be defined as the energy required when an electron is removed from a gaseous anion. The reaction as shown in equation 2.3.2.1 2.3.2.1 is endothermic (positive ΔU Δ U) for elements except noble gases and alkaline earth metals.
electron affinity, in chemistry, the amount of energy liberated when an electron is added to a neutral atom to form a negatively charged ion. The electron affinities of atoms are difficult to measure, hence values are available for only a few chemical elements, chiefly the halogens.
