En 1892, il succéda à son père à la présidence du Musée d'histoire naturelle, et en 1895, il devint professeur à l'École polytechnique. He had inherited from his father a supply of uranium salts, which phosphoresce on exposure to light. Biografi Kehidupan awal. Upon development, the photographic plate revealed silhouettes of the mineral samples, and, in subsequent experiments, the image of a coin or metal cutout interposed between the crystal and paper wrapping. Henri made this discovery when he left a piece of radio in his vest pocket and noticed that it had been burned. Biografi Kehidupan awal. He discovered this phenomenon while experimenting with uranium and a photographic plate. Discoverer of radioactivity. He undertook to investigate whether there was some fundamental connection between this invisible radiation and visible light such that all luminescent materials, however stimulated, would also yield X rays.

Henri Becquerel belajar ilmu pengetahuan alam di École Polytechnique dan teknik di École des Ponts et Chaussées.Pada tahun 1890, ia menikah dengan Louise Désirée Lorieux. He was elected a member of the French Académie des Sciences in 1889. He received his scientific education at the Ecole Polytechnique completing it in 1874. 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 entered the Polytechnic in 1872, then the government department of Ponts-et-Chaussées in 1874, becoming ingénieur in 1877 and being promoted to ingénieur-en-chef in 1894.

In 1896, French scientist Antoine Henri Becquerel discovered radioactivity which was an early contribution to atomic theory. 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. The mark of a great scientist is making grand discoveries almost unintentionally. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate. He also worked on the subject of terrestrial magnetism. Son of Alexandre Edmond Becquerel. Say FRENCH WORDS the FRENCH WAY !

When Ernest Rutherford and Frederick Soddy found similar decay and regeneration in thorium X and thorium, they were led to the transformation theory of radioactivity, which explained the phenomenon as a subatomic chemical change in which one element spontaneously transmutes into another. His son, Jean, became a physicist and studied the optical and magnetic properties of crystals. Please refer to the appropriate style manual or other sources if you have any questions.

His father, Alexander Edmond Becquerel, was a physicist who researched solar phenomena and phosphorescence. 1852 - 25. Need a pronunciation video ? To account for this novelty he postulated a long-lived form of invisible phosphorescence; when he shortly traced the activity to uranium metal, he interpreted it as a unique case of metallic phosphorescence.

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.
