What did Henry Moseley discover?
Moseley's law advanced atomic physics, nuclear physics and quantum physics by providing the first experimental evidence in favour of Niels Bohr's theory, aside from the hydrogen atom spectrum which the Bohr theory was designed to reproduce.
Feb 6, 2024 · Who was Henry Moseley and what was his relationship to the Periodic Table of the Elements? I became aware of Moseley’s death at the battle of Gallipoli when I was reading Richard Rhodes’s book “The Making of the Atomic Bomb” in 2008. There was also a picture of Moseley in his military uniform.

Henry Moseley was an outstandingly skilled experimental physicist. In 1913 he used self-built equipment to prove that every element's identity is uniquely determined by the number of protons it has. His discovery revealed the true basis of the periodic table and enabled Moseley to predict confidently the existence of four new
Just over 100 years ago, Henry Moseley carried out a systematic series of experiments which showed that the frequencies of the X-rays emitted from an elemental target under bombardment by cathode rays were characteristic of that element and could be used to identify the charge on its atomic nucleus.
Apr 7, 2020 · Testing every element he could get his hands on, from hydrogen to gold, Moseley showed that X-ray frequency increases as atomic numbers grow larger. Van den Broek was right. (Later, atomic numbers were found to equal the number of protons in the nucleus of each element.)
