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),
Finn (given name) Finn (given name) Finn is generally regarded as a masculine given name. The name has several origins. In some cases it is derived from the Old Norse personal name and byname "Finnr", meaning "Lapp" or "Finn". In some cases the Old Norse name was a short form of other names composed with this element. In other cases, the name "Finn" is derived from Irish, meaning "white" or "fair". In the later case, the name is an earlier Irish variant of "Fionn". It is also occasionally a female given name, although this is less common. People with the given name include:
