Henry Moseley Facts

Henry Moseley Facts
Henry Gwyn Jeffreys Moseley (23 November 1887 - 10 August 1915) was an English physicist. Moseley's experiments proved that the major properties of an element are due to its atomic number. He firmly established the relationship between the atomic number of an element and the charge of its nucleus.
Interesting Henry Moseley Facts:
Henry G.J. Moseley was born in Weymouth, England.
His father, Henry Nottidge Moseley, was a biologist and professor of anatomy and physiology at the University of Oxford.
Henry Moseley was awarded a King's scholarship to Eton College where in 1906 he won the chemistry and physics prizes.
In 1906 he entered Trinity College of the University of Oxford where he received his B.S. in 1910.
After graduation Moseley became an assistant to Sir Ernest Rutherford at the University of Manchester.
In 1912 Moseley experimented with radioactive beta particles and invented the first atomic battery.
In 1913 using X-ray spectroscopy he discovered Moseley's Law which states that there is a systematic mathematical relationship between the wave lengths of their X-rays and the atomic numbers of the metals used.
He was the first to use X-ray spectroscopy to measure the X-ray spectra of metals which was important in the invention of X-ray crystallography.
Before his discovery, atomic numbers were believed to be based on the sequence of atomic mass.
Moseley's Law correctly predicted the discovery of new elements at the numbers 43, 61, 72 and 75.
In early 1914 Moseley resigned from Manchester turned down a job offer to Oxford to enlist in the Royal Engineers.
He was serving as technical officer in communications during that Battle of Gallipoli in Turkey when, on 10 August 1915, he was killed by a sniper.
Because of Moseley's death, the British government no longer allowed its prominent scientists to serve in combat duty.
Moseley was a candidate for the 1916 Nobel Prize but it is not awarded posthumously; the Nobel Prize for Physics and the Nobel Prize for Chemistry were not awarded in 1916.
