Henry Moseley was an English physicist who made important discoveries about the structure of atoms and the organization of elements in the periodic table. His work in the early 1900s helped establish the fundamental relationship between an element's atomic number and its properties, which became crucial to modern chemistry and physics.

Encyclopedic overview
Henry Gwyn Jeffreys Moseley (/ˈmoʊzli/; 23 November 1887 – 10 August 1915) was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra.
Moseley's law advanced atomic physics, nuclear physics and quantum physics by providing the first experimental evidence in favour of Niels Bohr's theory, aside from the hydrogen atom spectrum which the Bohr theory was designed to reproduce. That theory refined Ernest Rutherford's and Antonius van den Broek's model, which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its (atomic) number in the periodic table.
