🔬 Chromium Properties
Chromium is hard, brittle, and highly corrosion-resistant. It has a high melting point (1907°C / 3465°F) and a reflective, mirror-like surface.
🧪 How Was Chromium Discovered?
In 1797, French chemist Louis Nicolas Vauquelin isolated Chromium from crocoite ore, identifying its vibrant red color as a new element.
