💡 Did you know? Radium was once used in glow-in-the-dark paint for watches and dials!
🔬 Radium Properties
Radium is radioactive, silvery-white, and reactive with water. It emits alpha, beta, and gamma radiation and glows faintly in the dark.
🧪 How Was Radium Discovered?
In 1898, Pierre and Marie Curie isolated Radium from uranium ore (pitchblende), naming it for its radiant properties.
