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),
Jane (given name) Jane (given name) Jane is a feminine given name. It is the English form of the Old French name Jehanne, which was an old feminine form of the male name Johannes or Ioannes (also the source of the English name John), a Latin form of the Greek name (Iōannēs), which is derived from the Hebrew name יוֹחָנָן (Yochanan), a short form of the name יְהוֹחָנָן (Yehochanan), meaning "Yahweh is merciful". The name was first used in large numbers in the mid-16th century for the daughters of aristocrats as an alternative to the more commonplace Joan. The two names have alternated
