WebApr 19, 2024 · There were further developments and discoveries that took place as recently as the first half of the 20th century. Henry Moseley is the most prominent contributor to the periodic table in the 20th century. A year before he died in World War 1, Moseley found that the X-ray wavelength of an element has a relationship with its atomic number. WebThrough this he discovered a systematic relation between wavelength and atomic number. This discovery is now known as the Moseley’s law. Moseley also predicted a number of missing elements and their periodic numbers in the Periodic Table. Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms.
