Quick Answer
Astatine was first synthesized in 1940.
The Full Story
Astatine was first synthesized in 1940 by Dale R. Corson, Kenneth Ross MacKenzie, and Emilio Segrè. They produced it by bombarding bismuth with alpha particles, creating a rare and highly radioactive element. Astatine is extremely scarce in nature, so it is mainly known through laboratory production and nuclear chemistry. It occupies one of the last places in the halogen group of the periodic table.
