Known as Moseley’s law, this fundamental discovery concerning atomic numbers was a milestone in advancing the knowledge of the atom. In 1914 Moseley published a paper in which he concluded that there were three unknown elements between aluminum and gold (there are, in fact, four). Statement of Moseley’s Law: “The square root of the frequency of the x-ray emitted by an atom is proportional to its atomic number. The frequency of a spectral line in the characteristics X-ray spectrum varies directly as the square of the atomic number of the element emitting it. rial. Use Moseley’s law to determine the atomic number of the target material.

Moseleys law

Using this law Moseley arranged K and Ar, Ni and CO in a proper way in Mendeleev's periodic table. This law was held to the discovery of many new elements like Tc (43), Pr (61), Rh (45). The atomic number of rare earth have been determined by this law. Moseley's empirical formula for K-alpha x-rays when adapted to the Bohr model becomes The implication of this relationship is that the single electron in the K-shell before the emission is almost 100% effective in shielding the nucleus so that the electron from the L-shell sees an effective nuclear charge of Z-1. Henry Gwyn Jeffreys Moseley 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 is quite accurate in predicting the energy of K X-rays for the ﬁrst row transitions metals, but it starts to deviate substantially as one moves to higher Z elements.

ⓘ Moseley’s Law [sqrt(v)] Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms. 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.
