In 1896, Henri Becquerel left Uranium salt in a desk drawer with a photograpic plates. Later he saw it and developed an outline of th clumps of urnanium salt. He hypothesized that the salt had emitted some unknown visible rays or radiation.
Henri Becquerel left Uranium salt in a drawer with some photographic plates. He observed it later and developed an outline of the groups. He thought that the salt had let of some radiation. That was in 1896.
Henri Becquerel left uranium salt in a desk drawer with photographic plaes in 1896. Later he saw it and developed an outline of the clumps of urnanium salt. He hypohthesized that the salt had emitted some unknown visible rays or radiation.
Henri Becquerel discovered it in 1896. He left uranium salt in a drawer with a photographic plate. When he developed the plate there was an outline of the uranium salt. He found that the outline was printed by radiation that darkened the film.
Henri Becquerel discovered it in 1896. He left uranium salt in a drawer wiht photographic plates. Later when he saw it he made an outline of the clumps of uranium salt. He thought that the salt ahd emitted some weird unknown rays or radiation.
Henri Becquerel discovered it. He left salt in a a drawer with hotographic plates. Later, he developed an outline of the clumps. he thought the salt had emitted some unknown visible rays.
It wasHenri Becuerel in 1896. He left Uranuim in a drawer on a photographic plate. When he developed it, there were traces of it. He thought that the uranium had left some unknown rays.
Henri Becquerel discovered radioactivity when he left a piece of Uranium salt in a desk drawer with photographic plates and there was an outline of the chunk of Uranium salt.
Henri Becquerel discovered this awesome scientifical evidence. He put Uranium salt on top of a photographic plate and put it in his desk drawer and closed it. He came back later and found out it had left an out line around the salt and figured that the salt had given off radiation. This was in 1896.

In 1896, Henri Becquerel was studying x-rays. When his project failed, he discovered that there was pure uranium where his project should have been. The uranium emitted radiation without an external source of energy such as the sun. Therefore, he discovered radioactivity.
Well the person who found this was Henri Becquerel and he left salt in a desk drawer with a photographic plate. he then observed it later and he developed an outline of the clmp of uranium salt. thats about all i got for you today!
Henri Becquerel used Uranium salt and left it in a desk drawer with a photographic plate. Later on he looked at the drawer and saw the developed outline of the clumps. He hypothesized radioactivity of th atoms.
Henri Becquerl left the uranium salt in a drawer with photographic plates then later he seen it and made an outline of groups in the uranium salt. He thought te salt left radiosctivity in it and this was in 1896.
Henre Becqyerel discovered it. because he left some uranium salt in a drawer aling with a photo plate. so then when he developed it it had some outlines like clumps of salt and that was how radioactivity was discovered.
Well i quess Becquerel, Henry Becquerel discovered radioactivity. This happened in 1896, he was right about what he hypothisized about and every thing, of salt.
in 1896 Henri Becquerel left uranium salt in a desk drawer with a photgraphic plate and then later when he went to develop the plate he found an outline of clumps of uranium salt he hypothesized that the uranium salt was emitting some unknown invisible rays of radiation.
Henri Becquerel had discovered radioactivity. HE had left salt in a desk drawer with some photographic plates. when he later found it it had developed an outline of the clumps of uranium salt. He had thought the the salt had emitted some unknown visible rays or radiation.
Henri Becquerel discovered radioactivity in 1896. He left uranium salt in a desk drawer with a photographic plate. Later when he developed the plate there was an outline of hte clumps of uranium salt on the plate. He hypthesized that the uranium salt had emitted an unknown invisible rays or radiation that darkened the film.
The person who discoverd it was Henri Becquerel and left uranium salt int a desk and photographic plates. Then he later saw it and develouped an outline of the clummps of uranium salt. He found out that salt had emmitted unknown rays that could be seen. He found this out in 1896.

the guy who discovered Radioactivity was Henri Becquerel in 1896.All he did it with was salt and a Photographic Plate
