⚛️ Atomic Structure of Praseodymium
Praseodymium has fifty-nine protons, eighty-two neutrons (in its only stable isotope, Praseodymium-141), and fifty-nine electrons, with three in its outer shell.
- 🟢 Protons: 59
- 🔴 Neutrons: 82 (Stable isotope, Praseodymium-141)
- 🟡 Electrons: 59
💡 Did you know? Praseodymium's name means "green twin" due to its color and discovery alongside neodymium!
🔬 Praseodymium Properties
Praseodymium is soft, malleable, and reactive. It melts at 931°C (1708°F) and oxidizes in air, forming a green oxide.
🧪 How Was Praseodymium Discovered?
In 1885, Austrian chemist Carl Auer von Welsbach separated Praseodymium from neodymium in a mixed rare earth sample, naming it from Greek "prasios" (green) and "didymos" (twin).
⚡ Uses of Praseodymium
