![]() He experimented with the wavelengths of certain metals that emitted x-rays, and he calculated the positive charges present in the nucleus of an atom. Moseley started his practice and research on the periodic table in 1913. The original periodic table was built in 1869 by Mendeleev, who arranged his table by atomic mass and had set it in ascending order. ![]() Dimitri Mendeleev made the first-ever periodic table, but it had errors and was not up to the mark Moseley researched and fixed the original mistakes. Today’s modern periodic table used by students and scientists alike is referred to as the ‘Henry Mosely periodic table’. He worked as a telecommunication officer until he died during the Battle of Gallipoli in 1915. He worked as a lecturer in the laboratory until he joined the army when World War I started. As a result of his excellent work, in 1910, he was accepted to be a lecturer of Physics at the University of Manchester in the laboratory of Ernest Rutherford. Henry Moseley completed his education at Trinity College in Oxford. While she was not a scientist, she was a chess champion. His mother also had a background related to science as she was the daughter of a famous Welsh biologist and conchologist. Henry’s father was a biologist and a professor at Oxford University, teaching anatomy and physiology there. His full name was Henry Gwyn Jeffreys Moseley. Henry Moseley was a physicist born in Waymouth, Dorset, in 1887. Henry Moseley’s periodic table is used even today for educational and research purposes. He helped refine the periodic table created by Rutherford and demonstrated that elements listed in the periodic table should be determined by their atomic numbers rather than their mass. Moseley helped make advancements in atomic, quantum and nuclear physics. He has extensively contributed his efforts in the field of Physics, and his studies helped shape physics as it stands today. She worked with Ernest Rutherford to gather the material now in the Museum’s archives in order to establish and preserve Moseley’s scientific and personal legacy.Henry Moseley was an English Physicist, and he was born in Waymouth, Dorset, in 1887. After Moseley’s tragic death in the Gallipoli campaign, his mother, Amabel, used her social diary to record her final moments with her son as well as the details of his death. Meanwhile, his experimental apparatus, hand-drawn technical diagrams, related documents and ephemera were preserved by Professor Townsend at the Oxford Department of Physics and transferred to the Museum in 1935. In October 1914, Moseley enlisted in the Royal Engineers as a signals officer. Moseley provided a new order to, and understanding of, the periodic table of chemical elements and contributed to the development of the nuclear model of the atom. Using X-ray spectroscopy, he discovered that every chemical element’s identity is uniquely determined by its atomic number, representing the positive charge on its nucleus. Spanning his time at Manchester and Oxford, he developed an experimental setup using ingenious apparatus of his own design to significantly change the world of science. Yet his life and career were cut short when he was killed in action at Gallipoli, Turkey, in August 1915, aged 27.ĭuring a scientific research career spanning a mere forty months, Moseley worked under Ernest Rutherford (1871–1937) at Manchester for three years before returning to his alma mater, Oxford, in November 1913. His work on the X-ray spectra of the elements provided a new foundation for the periodic table. ‘Harry’ Moseley (1887–1915) was an exceptionally promising young English physicist in the years immediately before the First World War. ![]() 17217 Amabel Moseley’s Collins pocket diary England, 1915 CE Moseley’s X-ray spectrometer Manchester, 1913 CE
