⚛️ Atomic Structure of Promethium
Promethium has sixty-one protons, eighty-four neutrons (in its most stable isotope, Promethium-145), and sixty-one electrons, with five in its outer shell.
- 🟢 Protons: 61
- 🔴 Neutrons: 84 (Most stable isotope, Promethium-145)
- 🟡 Electrons: 61
💡 Did you know? Promethium is the only naturally radioactive lanthanide, with no stable isotopes!
🔬 Promethium Properties
Promethium is soft, silvery, and radioactive. It melts at 1042°C (1908°F) and emits a faint blue-green glow due to beta decay.
🧪 How Was Promethium Discovered?
In 1945, American chemists Jacob A. Marinsky, Lawrence E. Glendenin, and Charles D. Coryell identified Promethium in uranium fission products at Oak Ridge, naming it after Prometheus, the fire-bringer of myth.
⚡ Uses of Promethium
