Uranium Properties and Applications
Uranium is a heavy, silvery-gray metallic element that is primarily known for its role in nuclear energy and weaponry. It is highly dense and radioactive, and it naturally occurs in several isotopic forms, with uranium-235 and uranium-238 being the most common. Uranium-235 is particularly valuable for nuclear fission due to its ability to sustain a chain reaction. The element is typically extracted from uranium ore and processed into fuel rods for nuclear reactors. Beyond energy production, uranium has applications in medical isotopes, military armaments, and research involving radioactive tracers.
Key Characteristics of Uranium
- Atomic number 92
- Symbol U
