WebChemists 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 … WebThe second electron affinity is a positive value as energy is needed to add a second electron to an ion with a pre-existing negative charge. This negative charge repels the incoming electron. Adding an electron is thus an endothermic process, and requires energy input. Electron Affinity Patterns on the Periodic Table

WebThe electron affinity of an atom or molecule is the propensity for that particle to gain an electron. This is an exothermic process for all non-noble gas elements. ... Although E ea varies greatly across the periodic table, some patterns emerge. Generally, nonmetals have more positive E ea than metals. Atoms, such as Group 7 elements, ... WebElectron Affinity: Electron Affinity is a property describing the tendency of a neutral atom to gain an electron, in order to form a negative ion. In this process, energy is released, also known as an exothermic process (excluding noble gases). A trend is observed, as elements further right a period and higher up a group have an increased ...
