Moseley's law definition, the observed law that the square root of the frequencies of lines in atomic x-ray spectra depends linearly on the atomic number of the emitting atom. See more. DICTIONARY.COM

Henry Moseley was an outstandingly skilled experimental physicist. In 1913 he used self-built equipment to prove that every element's identity is uniquely determined by the number of protons it has. Moseley’s law (i.e.,) provided a guideline to place the elements in the periodic table. Before the investigation of this law, elements were placed in the periodic in the increasing order of the atomic mass of the elements. But Moseley suggested that the characteristic properties of the element are determined by the atomic number (Z) of the 3 Moseley’s work showed that, in 1913, only four elements remained to be discovered that had lower atomic numbers than uranium.

[3] The frequency ν ν of characteristic X-rays is related to atomic number Z Z by Moseley's law, √ν = a(Z−b), ν = a (Z − b), which gives λ = c ν = c a2(Z− b)2. λ = c ν = c a 2 (Z − b) 2. Thus, the wavelength of emitted X-rays decreases with increase in Z Z. Moseley Plot of Characteristic X-rays. When the square root of the frequencies of the characteristic x-raysfrom the elements is plotted against the atomic number, a straight line is obtained. In his early 20's, Moseley measured and plotted the x-ray frequencies for about 40 of the elements of the periodic table. Henry Moseley.

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.
