2022: ☢️ Electron Affinity of Rubidium (Rb) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Rubidium 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 Rb?

In the case of Rubidium the electron affinity is 46.9 kilojoules per mole.  There are a lot of cool facts about Rubidium that most people don't know. Check this...
