He died instantly. Antoine Henri Becquerel (born December 15, 1852 in Paris, France), known as Henri Becquerel, was a French physicist who discovered radioactivity, a process in which an atomic nucleus emits particles because it is unstable. This was a colorless, radioactive gas given off by radium which could be used for sterilizing infected tissue. Which subatomic particle did James Chadwick discover? uranium. Curie's pioneering work on the theory of radioactivity and subsequent discovery of radium won her many accolades, but the financial cost of continuing her research on an element that had quickly become popular for its therapeutic properties was a formidable obstacle.
