How Can They Use Tennessine In Reactions? It Has A Half-Life Of 51 Milliseconds!
The chemistry textbook vs. element Ts (Tennessine) relationship status: "It's complicated." While textbooks casually discuss converting hydroxyl groups into tosylates for better leaving ability, Tennessine is over here decomposing before you can even finish reading its name. With a half-life of 51 milliseconds, Ts atoms are basically the chemical equivalent of "sorry, I ghosted you—I literally ceased to exist." Chemists be like "let me just grab some Tennessine for this reaction" and the Tennessine responds by transforming into something else before they can even put on their safety goggles. Talk about commitment issues!
