WebMoseley’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. Equation (2) can be derived by solving Schr€odinger’s equa-tion for an atomic system with an infinitely heavy nucleus and one electron. WebAug 11, 2024 · Just two years later, in 1913, English physicist Henry Moseley (1887-1915) examined x-ray spectra of a number of chemical elements. He would shoot x-rays through crystals of the element and study the wavelengths of the radiation that he detected. Moseley found that there was a relationship between wavelength and atomic number. dr rick gill troy al https://chepooka.net
