[PAR] [TLE] Moseley's law [SEP] Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms.  The law was discovered and published by the English physicist Henry Moseley in 1913.  It is historically important in quantitatively justifying the conception of the nuclear model of the atom, with all, or nearly all, positive charges of the atom located in the nucleus, and associated on an integer basis with atomic number.  Until Moseley's work, "atomic number" was merely an element's place in the periodic table, and was not known to be associated with any measureable physical quantity.  Moseley was able to show that the frequencies of certain characteristic X-rays emitted from chemical elements are proportional to the square of a number which was close to the element's atomic number; a finding which supported Van den Broek and Bohr's model of the atom in which the atomic number is the same as the number of positive charges in the nucleus of the atom.  In brief, the law states that the square root of the frequency of the emitted x-ray is proportional to the atomic number. [PAR] [TLE] Henry Moseley [SEP] Henry Gwyn Jeffreys Moseley (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 justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a logical order based on their physics.  He published first the Long Form periodic table or Modern periodic table which is used till date.
