This chemistry video tutorial provides a basic introduction into electron affinity. it discusses the general trend of electron affinity as well as its many exceptions. Electron affinity is the energy change that occurs when a gaseous atom receives an electron. This video discusses which elements have electron affinity values that are endothermic and which ones are exothermic. Noble gases and alkaline earth metals are mostly endothermic. Halogens and chalcogens are mostly exothermic.
