=Becquerel's earliest work was concerned with the plane polarization of light, with the phenomenon of phosphorescence and with the absorption of light by crystals (his doctorate thesis). He also worked on the subject of terrestrial magnetism. In 1896, his previous work was overshadowed by his discovery of the phenomenon of natural radioactivity. Following a discussion with Henri Poincaré on the radiation which had recently been discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum tube, Becquerel decided to investigate whether there was any connection between X-rays and naturally occurring phosphorescence. He had inherited from his father a supply of uranium salts, which phosphoresce on exposure to light. When the salts were placed near to a photographic plate covered with opaque paper, the plate was discovered to be fogged. The phenomenon was found to be common to all the uranium salts studied and was concluded to be a property of the uranium atom. Later, Becquerel showed that the rays emitted by uranium, which for a long time were named after their discoverer, caused gases to ionize and that they differed from X-rays in that they could be deflected by electric or magnetic fields. For his discovery of spontaneous radioactivity Becquerel was awarded half of the Nobel Prize for Physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation
Lavoisier is not known for an atomic theory.
Lavoisier made the atomic theory of matter, stating that matter is not destroyed or created, just changes form.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
Atomic theory including the stricter of atOms in terms of protons and neutrons and electrons
revived the atomic theory and stated the law of Partial Pressures of gases
Lavoisier is not known for an atomic theory.
he contributed by creating milk
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
Dalton is credited for his expanding and formulating the modern atomic theory, but it was Jouseph Louis Proust and Antoine Lavoisier who are cited as initially discovering it.
Antoine Lavoisier was a chemist and physicist in the late 1700's. Widely considered to be the Father of Chemisty, his contribution to the atomic model was the Combustion Theory and the beginnings of the Law of Conservation of Mass.

when i was atomic theory i was a smart
Atomic theory was founded by John Dalton. He proved this theory in 1803.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
They didn't help with atomic theory, they created it.
