🔬 Lutetium Properties
Lutetium is hard, dense, and reactive. It melts at 1663°C (3025°F), resists corrosion better than most lanthanides, and oxidizes slowly.
🧬 How Was Lutetium Discovered?
In 1907, French chemist Georges Urbain and Austrian scientist Carl Auer von Welsbach independently isolated Lutetium from ytterbium, naming it after Lutetia, the Latin name for Paris.
