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.

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 …

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.

Aug 31, 2022 · Electron affinity (Eea) is the energy change when a neutral atom in the gas phase gains an electron. In simple terms, it is a measure of a neutral atom’s ability to gain an electron.

The electron affinity of an element is a measure of that element’s tendency to act as an oxidizing agent (an electron acceptor) and is generally related to the nature of the chemical bonds the …

The electron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion. For example, when a neutral chlorine atom in the gaseous form …

Jul 23, 2025 · Electron affinity is the energy change that occurs when an electron is added to a neutral atom to form a negatively charged ion. It measures the attraction between the …

Electron affinity refers to the energy released when an additional electron is attached to a neutral atom to form a singly charged negative ion. Alternatively, it can also be defined as the energy …

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 affinity is the enthalpy change when an atom captures an electron. By definition this process is written for gas-phase species so that the value reflects only the interaction between …
