2022: ☢️ Electron Affinity of Selenium (Se) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Selenium is defined as the amount of energy released or spent when an electron is added to a neutral atom in the gaseous state to form a negative ion. But what is the electron affinity of an atom of Se?

In the case of Selenium the electron affinity is 195 kilojoules per mole.  There are a lot of cool facts about Selenium that most people don't know. Check this...
