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 …

Dec 9, 2025 · Chemical bonding - Electron Affinity, Intermolecular Forces, Covalent Bonds: Third in importance for bond formation after size and ionization energy is the energy change …

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.

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 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 …
