Which chemical element was originally known as Alabamine?

The chemical element originally known as Alabamine is Astatine. It was first identified in 1940 by American scientists, Emilio Segrè and Dale R. Corson, who initially named it Alabamine after the city of Alabam, Alabama. However, just a few months later, British scientists who also discovered the element decided to rename it Astatine, derived from the Greek word "astatos" meaning unstable, due to its highly reactive and unstable nature. Thus, Alabamine became known as Astatine, which is its recognized name in the field of chemistry today.
