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.

Dec 9, 2025 · Third in importance for bond formation after size and ionization energy is the energy change accompanying the attachment of electrons to a neutral atom. This energy is expressed …

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 …

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 …

Aug 29, 2025 · A key characteristic influencing atomic interactions is electron affinity, which describes an atom’s propensity to gain an additional electron. Understanding this atomic …

Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom. The second (reverse) definition is that …

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 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 …
