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.

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.

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.

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.

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 …

Dec 9, 2025 · This energy is expressed as the electron affinity, which is the energy released when an electron is attached to an atom of the element. In many cases, the electron affinity is positive, …

The electron affinity of an element is the energy released when an electron is added to a neutral atom of that element in the gas state, to form a singly negative ion (it is also called the first electron affinity).

Electron affinity is a measure of how strongly a neutral atom or molecule attracts an additional electron, reflecting its ability to form negative ions. This property plays a crucial role in understanding various …

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.

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 …
