🔬 Bismuth Properties
Bismuth is brittle, dense, and has a low melting point of 271.5°C (520.7°F). It resists corrosion and expands when it solidifies.
🧪 How Was Bismuth Discovered?
In 1753, French chemist Claude Geoffroy distinguished Bismuth from lead and tin, though it was known earlier. Its name may derive from German "wismut" (white mass).
