The element that has a high electron affinity from Xe and Cs should be predicted. Concept Introduction: The amount of energy required to add an electron to the atom to form negative ion is known as electron affinity. The factors affecting electron affinity are shown below: It is inversely proportional to the size of an atom. It is directly proportional to the effective nuclear charge. It is inversely proportional to the stable electronic configuration.
