WebNext Video 8.6: Alkali Metals 8.5: Electron Affinity The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion). This process can be either endothermic or exothermic, depending on the element. WebWhat is Electron Affinity? 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. This process differs from electronegativity, which we define as the ability of an atom to attract an electron toward itself.

WebJasmine Grover. Electronegativity is the capacity of an atom to attract electrons from the outside, whereas electron affinity is the amount of energy released when an atom receives an electron. A subatomic particle of an atom is known as an electron. Since all matter is made up of atoms, electrons may be found everywhere. WebJan 30, 2024 · Electronegativity. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to cesium and francium which are the least electronegative at 0.7.
