🔬 Samarium Properties
Samarium is hard, brittle, and reactive. It melts at 1072°C (1962°F) and slowly oxidizes in air, forming a grayish coating.
🧪 How Was Samarium Discovered?
In 1879, French chemist Lecoq de Boisbaudran isolated Samarium from samarskite ore via spectroscopy, naming it after the mineral.
