In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
Henry Moseley discovered a relation between X-ray spectra and the atomic number of chemical elements.
Henry Gwyn-Jeffreys Moseley in the 1910s.
he knew that it had protons and neutrons and electrons but he thaught the charges where the wrong way round

Henry Moseley.
Henry Moseley discovered a relation between the atomic number and the X-ray wavelength of a given chemical element; this was a physical confirmation of the periodic table and the order of elements in the table.
Henry Moseley sorted the chemical elements on the Periodic Table in order by their atomic numbers. Moseley was a British chemist who had studied under Rutherford.
