⚛️ Atomic Structure of Cerium
Cerium has fifty-eight protons, eighty-two neutrons (in its most common isotope, Cerium-140), and fifty-eight electrons, with four in its outer shell.
- 🟢 Protons: 58
- 🔴 Neutrons: 82 (Most common isotope, Cerium-140)
- 🟡 Electrons: 58
💡 Did you know? Cerium sparks when struck, making it key in lighter flints!
🔬 Cerium Properties
Cerium is soft, ductile, and reactive. It melts at 795°C (1463°F) and oxidizes quickly in air, forming a protective layer.
🧪 How Was Cerium Discovered?
In 1803, Martin Heinrich Klaproth (Germany) and Jöns Jakob Berzelius with Wilhelm Hisinger (Sweden) found Cerium in cerite ore, naming it after the asteroid Ceres.
⚡ Uses of Cerium
