Electron Affinity of Thulium (Tm) [& Color, Uses, Discovery ... 2022

In chemistry, the electron affinity of an atom of Thulium 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 Tm?

In the case of Thulium the electron affinity is 50 kilojoules per mole.  There are a lot of cool facts about Thulium that most people don't know. Check this...
