Did Henri Becquerel and the Curies find out that the atoms werent indivisible?
Yes, Henri Becquerel and the Curies discovered that atoms were not indivisible when they conducted experiments on radioactivity. They found that certain elements could spontaneously emit radiation, demonstrating that atoms were composed of even smaller particles. This discovery led to the development of the field of nuclear physics.
How did Antoine Becquerel improve the atomic theory?
=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
What is the difference in atomic number between the original isotope of uranium that begins the decay series and the final isotope of lead?
The original isotope of uranium in the decay series is uranium-238, which has an atomic number of 92. The final isotope in the decay series is lead-206, which has an atomic number of 82. Therefore, the difference in atomic number between uranium-238 and lead-206 is 10.
What formula describes how naturally occurring chemical elements such as uranium thorium and potassium helped to heat the Earth's interior?
During radioactive decays heat is released.
What helped scientist determine the age of the universe?
The redshift of the cosmic microwave background radiation

Which scientists helped to determine the shape of DNA?
The scientists who helped determine the shape of DNA were James Watson and Francis Crick.
Which scientist helped to determine the shape of DNA?
The scientist who helped determine the shape of DNA was James Watson, along with Francis Crick.
Henri Becquerel and the Curies found out that?
Henri Becquerel and the Curies discovered that some elements, like uranium and radium, emitted radiation spontaneously, leading to the development of the field of nuclear physics. This groundbreaking research laid the foundation for the understanding of radioactivity and its applications in various fields, including medicine and energy production.
Who was the women to win Nobel Prize in physics in 1903?
Marie Curie won the Nobel prize in 1903 for physics, along with Pierre Curie (her husband), and Henri Becquerel who helped with the discovery of radiation.

How those the ocean keep the temperature mild in both summer and winter?
The ocean keeps the temperature mild in summer and winter by, in summer, extracting heat from the air to warm up the waters temperature, then in winter, the heat radiates off the ocean. By the end of winter, the water is colder from the cold air, and radiates it off in summer. Hope that helped.

Who was the woman who discovered Radium?
Marie Curie also discovered polonium. Her husband Pierre helped in the investigation also. She started off by studying a variety of chemical compounds that contained uranium. She discovered that the strength of the rays that came out depended only on the amount of uranium in the compound. It had nothing to do with whether the material was solid or powdered, dry or wet, pure or combined with other chemical elements. If you had a certain amount of uranium a certain number of uranium atoms-then you got a certain intensity of radiation. Nothing else made a difference. The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity",the other half jointly to Pierre Curie and Marie Curie.
Can you give of a person discovered radioactivity?
The early discovery of Radioactivity goes to a Frenchman named Henri Becquerel . In 1896, Henri got some natural fluorescent minerals to be experimented upon. The main purpose he wanted to experiment was to study on the x-ray properties which had already been discovered a year ago and he wanted to examine further. This experiment helped him to expose potassium uranyl sulfate to the rays of the sun believing that the energy of the sun would probably be absorbed by Uranium and them emit it outwards as X-Rays. Since there were changes in weather, the experiment had failed because the day was overcast. There came a physicist named Marie Curie who made a great contribution to the discovery of Becquerel. Curie was the man who actually coined the radioactivity term. Hope this helps.
