A higher electron affinity is associated with more tendency to accept electrons, while a lower … WebThe chemical equation for electron affinity is as follows [1-4]. X (g) + e – → X – (g) When an electron approaches a neutral atom, the positively charged nucleus attracts it. The atom transforms into a negatively charged ion or an anion. Consequently, energy is released in this process, making the process exothermic. le juliana

WebElectron affinity measures the ease of gaining an electron by an atom. For example, the electron affinity of chlorine is −348.6 kJ/mol. The negative sign indicates that it is an exothermic change. Argon, however, has a positive electron affinity, indicating that formation of an argon anion requires energy to be supplied. WebThe amount of energy released when an atom in the gaseous state accepts an electron to form an anion. Factors which affect electron affinity are: Atomic size and Nuclear charge. As atomic radii increases, electron affinity increases. As nuclear charge increases, electron affinity increases. It decreases down a group and increases across a period.
