🔬 Astatine Properties
Astatine is radioactive, likely metallic, and dark. It melts around 302°C (576°F, estimated), but its short half-life makes it hard to study.
🧪 How Was Astatine Discovered?
In 1940, Dale R. Corson, Kenneth Ross MacKenzie, and Emilio Segrè synthesized Astatine at UC Berkeley, naming it from Greek "astatos" (unstable).
