On This Day In Chemistry

March 2nd

French physicist Henri Becquerel announced the discovery of radioactivity on this day in 1896

Becquerel discovered that potassium uranium sulfate crystals can produce images on photographic plates even when kept in the dark. He deduced that the crystals must spontaneously emit radiation, which earned him the Nobel Prize in Physics in 1903 along with Marie Curie.
