=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

Antoine Becquerel discovered radioactivity in 1896, which led to the development of the subatomic theory. This discovery provided evidence that atoms are composed of smaller particles, like protons, neutrons, and electrons, and helped expand our understanding of the structure of atoms and their behavior.

What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
How does Antoine lavoisier relate to the atomic model development?
Antoine Lavoisier is known as the father of modern chemistry for his work on the law of conservation of mass and the discovery of the role of oxygen in combustion. Although he did not directly contribute to the development of the atomic model, his work laid the foundation for future researchers like John Dalton to further investigate the concept of atoms and atomic theory.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
What important contribution did Lavoisier make to Dalton's atomic Theory of Matter?
What important contribution did Lavoisier make to Dalton's atomic theory of matter? Lavoisier helped the atomic theory of matter, by stating that matter is not destroyed or created, it just changes form. Located inside the nucleus, has a positive charge, and 1 amu.
What did henri becquerel contribute to the atomic theory?
Henri Becquerel discovered radioactivity in 1896, which was a significant contribution to the atomic theory by demonstrating that atoms could spontaneously change and emit radiation. This discovery paved the way for further research into the structure of the atom and the development of nuclear physics.
What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
What was Antoine-laurent lavoiser's contribution to atomic theory?
he contributed by creating milk
What was Lavoisier's contributions to the development of the modern atomic theory?
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.
Did John Dalton discover the Atomic Theory?
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.
What was Antoine Lavoisier's contribution to the atomic model?
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.

Antoine Lavoisier
How can an stm help improve daltons theory?
An STM (scanning tunneling microscope) can help improve Dalton's atomic theory by providing visual evidence of individual atoms and their arrangements on surfaces. This experimental data can offer insights into the precise structure and behavior of atoms, supporting or refining Dalton's ideas based on empirical observation. Additionally, STM allows for the direct observation of atomic interactions and bonding, which can lead to a deeper understanding of atomic behavior beyond what Dalton's theory originally proposed.
How Do You Use The Word atomic theory in A Sentence?

Atomic theory invented by?
Atomic theory was founded by John Dalton. He proved this theory in 1803.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
