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 neutral atom's …

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 amount of energy released when a neutral atom in its gaseous state accepts an electron and gets converted into a negatively charged ion is known as electron affinity.

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

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 incoming electron and …

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 element forms …

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 required to …

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 picks up an …

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 the incoming …
