Henry Moseley
Henry G. J. Moseley, known to his friends as Harry, was born in Weymouth in Dorset in 1887. His father Henry Nottidge Moseley (1844–1891), who died when Moseley was quite young, was a biologist and also a professor of anatomy and physiology at the University of Oxford, who had been a member of the Challenger Expedition. Moseley's mother was Amabel Gwyn Jeffreys, the daughter of the Welsh biologist and conchologist John Gwyn Jeffreys. She was also the British women's champion of chess in 1913.

what is the purest form of iron called UNANSWERABLE what is this subsance? It is a chemical element with symbol Fe and atomic number 26. what is this number? Also known as the proton number (symbol "Z") of a chemical element - it is the number of protons found in the nucleus of every atom of that element. how is it related to an experiment conducted in 1913? The experimental position improved dramatically after research by Henry Moseley in 1913. who was this person? He was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. where was he from? Weymouth in Dorset what was his role towards explaining the atomic structure? His discovery showed that atomic numbers were not arbitrarily assigned, but rather, they have a definite physical basis. what was his role in the field of x-rays? The X-ray spectrometers as Moseley knew them worked as follows. A glass-bulb electron tube was used, similar to that held by Moseley in the photo here. Inside the evacuated tube, electrons were fired at a metallic substance (i.e. a sample of pure element in Moseley's work), causing the ionization of electrons from the inner electron shells of the element.

Henry Moseley [SEP] Biography
In 1906 he won the chemistry and physics prizes at Eton. In 1906, Moseley entered Trinity College of the University of Oxford, where he earned his bachelor's degree. While an undergraduate at Oxford, Moseley joined the Apollo University Lodge. Immediately after graduation from Oxford in 1910, Moseley became a demonstrator in physics at the University of Manchester under the supervision of Sir Ernest Rutherford. During Moseley's first year at Manchester, he had a teaching load as a graduate teaching assistant, but following that first year, he was reassigned from his teaching duties to work as a graduate research assistant. He declined a fellowship offered by Rutherford, preferring to move back to Oxford, in November 1913, where he was given laboratory facilities but no support.
