The results of his study showed a clear and simple progression of the elements that was based on the number of protons in the atomic nucleus, rather than the order based on atomic weights that was then the basis of the Periodic Table. Moseley returned to Oxford, and despite the experimental deficiencies of his laboratories, measured the x-ray spectral lines of nearly all the elements from aluminum to gold. Their work demonstrated that the spectral line of platinum, which they were using as the anticathode in their x-ray tube, was characteristic of that element alone. Darwin, to further study the nature of x rays. Moseley persuaded Rutherford to allow him and a colleague, C. Bragg the same year showed that similar results could be obtained by the reflection of x rays from the face of a crystal. The nature of x rays was also receiving new interest because of the discovery by the German physicist Max von Laue in 1912 that they were diffracted by their passage through crystals and therefore possessed a wave nature. The first coherent theory of the structure of the atom was just then being developed by Rutherford and his research group, which, besides Moseley, included Niels Bohr, Hans Geiger, Kasimir Fajans, and others. It was a time of great excitement and ferment in science, and Rutherford's laboratory was one of the epicenters of discovery in atomic physics. He graduated in 1910 with high honors in mathematics and science, and secured a position in the laboratory of Ernest Rutherford at the University of Manchester. At that time, Oxford did not have a particularly notable science curriculum, but Moseley chose the school in order to be near his widowed mother. He entered Trinity College, Oxford, in 1906. He attended Eton on a King's scholarship, where he excelled in mathematics, and was introduced to the study of x rays by his physics teacher. His family was wealthy, aristocratic, and scientifically accomplished, and young Henry showed an early interest in zoology. Henry Gwyn Jeffreys Moseley, who was always called "Harry" by his family, was born in Weymouth, England, on November 23, 1887. But in his classic study of the x-ray spectra of elements, he established the truly scientific basis of the Periodic Table by arranging chemical elements in the order of their atomic numbers. 2016.Henry Moseley's research career lasted only forty months before tragically ending with his death on a Gallipoli battlefield in World War I. No Nobel prizes were awarded to him but many people believe that if he would have been alive he would have won one of these awards. Due to his death the British government placed a ban on other scientist of refute joining the front lines. Henry Moseley was killed in battle Augat age 27. He family pleaded with him not to go and the army was reluctant as well. World War I began and Moseley quickly enlisted in the British army's royal engineers. He also discovered that the basic difference between elements is the number of protons they had. Moseley tested this theory by shooting electrons at chemical elements and proved this to be correct, completely changing the periodic table. Previous to Moseley a scientist had made a hypothesis that atomic number could actually be the amount of charge in the atom's nucleus. Gaining confidence in the field he started to come up with his own experiments. Working with Rutherford, Moseley became very familiar with radioactive chemical elements. Luckily for him Rutherford offered Moseley a research fellowship, allowing him to focus solely on research. Not to long after he realized that teaching was not for him. In Manchester Moseley taught physics while still carrying out his research work. Disappointed In his performance here he moved to the university of Manchester in 1910 to join Ernest Rutherford's research group. After much success at Eton college he was admitted to the university of oxford’s trinity college in 1906. Henry got a scholarship to Eton college which is arguably Britain's most prestigious high school. His father was a professor of anatomy and physiology and his mom was a mollusc biologist. Henry Moseley was born in Weymouth England on November 23 1887.
