Quick Scoop

  • In 1898, Marie and Pierre Curie isolated a new highly radioactive substance from the mineral pitchblende and identified it as a new element, which they named radium.
  • They extracted about 1 milligram of radium from several tons of uranium ore, proving its existence through its unique radiation and spectral lines.
  • The discovery of radium, along with their work on polonium and radioactivity, led to their Nobel Prize in Physics in 1903 and later a Nobel Prize in Chemistry for Marie Curie in 1911.

TL;DR: Radium was discovered by Marie and Pierre Curie in 1898 during their pioneering research on radioactivity.
