radium | Description, Properties, Symbol, Uses, & Facts ...

Radium thus occurs in all uranium ores, but it is more widely distributed because it forms water-soluble compounds; Earth's surface contains an estimated 1.8 × 10 13 grams (2 × 10 7 tons) of radium. Since all the isotopes of radium are radioactive and short-lived on the geological time scale, any primeval radium would have disappeared long ago.
