The Elements: Uranium

Uranium, named after the planet Uranus, has the second highest atomic mass among natural elements, only surpassed by plutonium. It is weakly radioactive and a major heat source inside Earth. Found in low concentrations, uranium is more abundant than silver. Historically, uranium-colored glass was prized. Today, its nuclear properties are crucial for power generation and military uses. Uranium decays slowly, with Uranium-238 having a half-life over 4 billion years, aiding in Earth's age estimation.
