Electron Affinity

The amount of energy absorbed in the process in which an electron is added to a neutral isolated gaseous atom to form a gaseous ion with a 1- charge; has a negative value if energy is released.

Electron Affinity

The measure of an atom's tendency to gain an electron. Thermal energy is released from most atoms when they gain an electron. The higher the electron affinity number, the more likely to gain an electron.

electron affinity

The energy released when an additional electron (without excess energy) attaches itself to a molecular entity (usually an electrically neutral molecular entity). (The direct measurement of this quantity involves molecular entities in the gas phase.)

electron affinity

Electron affinity (EA) is the energy change occurring when an atom or molecule gains an electron to form a negative ion. For an atom or molecule X, it is the energy released for the electron-attachment reaction X(g) + e- X- (g) Often this is measured in electronvolts. Alternatively, the molar enthalpy change, ?H, can be used.

Electron affinity

[data page] == Elements == Electron affinity can be defined in two equivalent ways. First, as the energy [that is] released by adding an electron to a gaseous atom. (The energy -or electron affinity- is a scalar quantity and the direction of that energy -released- defines a reaction for which the change in energy ΔE is a negative quantity)

Electron affinity

In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion. In solid state physics, the electron affinity for a surface is defined somewhat differently (see below). ==Measurement and use
