Antoine Henri Becquerel was a French scientist who made significant contributions to the field of physics and the understanding of radioactivity. Born in Paris in 1852, Becquerel was the son of Alexandre-Edmond Becquerel, a renowned physicist and engineer. He followed in his father's footsteps and pursued a career in science, ultimately becoming a professor of physics at the Sorbonne in Paris.
One of Becquerel's most significant contributions was his discovery of radioactivity, which he made in 1896 while studying the properties of phosphorescent materials. He found that certain substances, such as uranium, emitted an unusual form of energy that could pass through solid objects and fog. This energy was later identified as radiation, and Becquerel's discovery marked the beginning of the field of radioactivity.
In addition to his work on radioactivity, Becquerel made important contributions to the understanding of the structure of atoms. He discovered that the energy emitted by radioactive substances came from the transformation of atoms, and he helped to establish the concept of the atomic nucleus. Becquerel also developed the theory of radioactive decay, which explained how atoms of certain elements could spontaneously transform into atoms of different elements.
Becquerel's work on radioactivity and the structure of atoms had a significant impact on the development of modern physics and technology. His discoveries paved the way for the development of nuclear energy and the understanding of the fundamental nature of matter. In 1903, Becquerel was awarded the Nobel Prize in Physics for his work on radioactivity, along with Marie Curie and Pierre Curie.
In conclusion, Antoine Henri Becquerel made important contributions to the field of physics through his discovery of radioactivity and his work on the structure of atoms. His research laid the foundation for the development of nuclear energy and the understanding of the fundamental nature of matter, and he is remembered as a pioneer in the field of physics.
One week later, on March 2, 1896, Becquerel was back before the French Academy with the results of his further experiments. Becquerel belonged to a family of scientists and scholars. The Evolution of Chemistry: A History of Its Ideas, Methods, and Materials. Becquerel could not expose his uranium salts to sunlight for several days because there was no sunshine. The material Becquerel chose to work with was a double sulfate of uranium and potassium which he exposed to sunlight and placed on photographic plates wrapped in black paper. By his working hypothesis, that would have been impossible because the luminescence of potassium uranyl sulfate ceases immediately when the He did not neglect his general studies.
Retrieved 12 March 2018. On those rare occasions when Becquerel did pursue a hypothesis, this critical power continually corrected his enthusiasms and redirected his line of investigation; so that, for example, while he persistently searched for X rays in phosphorescence, he managed to discover the inherent radioactivity of uranium. Several days later, when Becquerel finally removed the plate from the drawer, he discovered to his surprise that a distinct image of the cross appeared on the plate — although it had never been exposed to sunlight. Retrieved 25 April 2018. That Becquerel became a scientist was of no surprise to his family--both hisfather and grandfather before him had been physicists. Retrieved 6 March 2018.
Henri Becquerel was a French scientist, physicist and one of the most important personalities in the history of radioactive research. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Because he had double-boxed his plates inside his dark room and had placed the ensembles inside a drawer that he then closed, he was able to conclude that his mysterious rays were not related to phosphorescence and were not induced by sunlight. One hypothesis which presents itself to the mind naturally enough would be to suppose that these rays, whose effects have a great similarity to the effects produced by the rays studied by M. Antoine Henri Becquerel Henri Becquerel was born into a family of scientists. Developing the photographic plates, Becquerel observed an intensely defined silhouette on the first two plates, and a clear but considerably weaker silhouette on the third.
Thanks to the following group for allowing us to reprint this information: 1313 Dolley Madison Blvd. Becquerel decided to probe his unusual rays a little further. To his surprise, the images were clear and strong. With his doctorate achieved, Becquerel became substantially inactive in research. On 2 March he reported comparable exposures when both crystals and plate lay in total darkness.

For his discovery of radioactivity, Becquerel was awarded the 1903 Nobel Prize for physics.
He thus confirmed his view that something very similar to X rays was emitted by this luminescent substance at the same time it threw off visible radiation. Since the sun did not come out in the following days, I developed the photographic plates on the 1st of March, expecting to find the images very weak. Retrieved 12 March 2018. Nevertheless, he devoted a substantial effort to searching out the radiation that had first excited his penetrating rays. And so, upon learning how Wilhelm Röntgen discovered X rays by observing the fluorescence they produced, Becquerel had a ready source of fluorescent materials with which to pursue his own investigations of these mysterious rays. Becquerel became their liaison to the scientific world, presenting papers documenting their progress to the Academy of Sciences. Nevertheless, this X-ray hypothesis caught his fancy.
Henri Becquerel and Marie Curie contribution to radioactivity
Of more importance, he had shown that the power of emitting penetrating rays was a particular property of uranium. Though many were to follow him, Henri Becquerel was the first toexperiment with radioactivity. Further studies made it clear that this radiation was something new and not X-ray radiation: he had discovered a new phenomenon, radioactivity. Henri Becquerel, born Dec. Content to teach at the École Polytechnique, he ceased his experimentation, at least temporarily. Becquerel received a doctorate degree from the Faculty of Sciences of Paris in 1888.
