Proton from different gases had different values of charge-to-mass ratio (e/m), they could not be identified with a single particle, unlike the negative electrons discovered by J. J. Thomson. Wilhelm Wien in 1898 identified the hydrogen ion as particle with highest charge-to-mass ratio in ionized gases. Following the discovery of the atomic nucleus by Ernest Rutherford in 1911, Antonius van den Broek proposed that the place of each element in the periodic table (its atomic number) is equal to its nuclear charge. This was confirmed experimentally by Henry Moseley in 1913 using X-ray spectra. In 1917 (in experiments reported in 1919),
Alan (given name) is today Russia, and who were known to Classical writers in the 1st century CE. According to historian Bernard Bachrach, the Alans settled in parts of what is today France, including Brittany, in the Early Middle Ages. Bachrach stated that the use of forms of the name in given names, surnames, and place names, are evidence of the continued influence of the Alans on the Gaulish, Breton and Frankish peoples. The Breton name "Alan" can not be a direct loan from the ethnic name of the Alans (rendered as "Alānī" or "Halānī" in Latin, from Scytho-Sarmatian "*Al[l]ān-", derived from Old
