Antoine Henri Becquerel: His part of the Atomic theory
8
His reward:
Even though he had discovered radioactivity, he hadn't
pursued into it. Instead Marie and Pierre Curie did most
of the studies on radioactivity. There fore the three had split the Nobel Prize of Physics in 1903.
Biography:
Becquerel was born in Paris,
the 15th of December 1852.
His father and grandfather were
professor for physics, so he followed
in their footsteps to become a scientist,
physicist, and professor.
He had been a professor for the polytechnic
University.
The date of his death was August 25, only when
he was 55 years old.

Experiment to the discovery:
He wanted to prove his hypothesis that the x-ray might have a connection with naturally occurring phosphorescence. So he collected uranium that phosphoresce in solar radiation, when expose to sunlight the uranium would ionize and create a figure in photographic paper.
But this required the sun, and the day he tried this experiment it was cloudy, so leaving it in a drawer. But retrieving it later he found that the paper still had images of the salts, discovering that the uranium releases gases that ionized and were deflected by electric. He discovered that radiation did not only come from the sun, which lead to his huge discovery: spontaneous radioactivity.
