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),
Kennedy (given name) Kennedy (given name) Kennedy is a unisex given name in the English language. The name is an Anglicised form of a masculine given name in the Irish language. According to Patrick Hanks and Flavia Hodges, the given name "Kennedy" is an Anglicised form of "Cinnéidigh", a masculine given name in the Irish language. This Irish name is composed of two elements: the first, "ceann", means "head"; the second, "éidigh", means "ugly". According to Patrick Woulfe, who wrote in the early 19th century, "Kennedy or Kynidi" is an Anglicised form the Irish "Cinnéididh" and "Cinnéidigh". Woulfe derived these Irish names from
