	Henry Gwyn Jeffreys Moseley - LoveToKnow 1911 (Site not responding. Last check: 2007-10-10)
		Moseley, shortly after the discovery of the diffraction of X-rays by crystals, set to work to examine the X-ray spectrum of a number of elements each of which he made in turn the target of an X-ray tube.
		He found that his crystal-grating gave a spectrum of two lines for each element and that their frequency increased by definite steps ashepassed from one element to the next; indeed, the frequency of vibration associated with each element was a simple function of a number which he found to be identical with the atomic number.
		Moseley was in Australia with the British Association in 1914 when the World War broke out; he returned to England, obtained a commission in the Royal Engineers, and was killed by a Turkish bullet on the Gallipoli peninsula on Aug. Io 1915.

	Henry Moseley
		Henry Gwyn Jeffreys Moseley (November 23, 1887-June 15, 1915) was an English physicist.
		Moseley's discovery showed that atomic numbers were not arbitrary but had an experimentally measurable basis.
		In addition, Moseley showed that there were gaps in the sequence at numbers 43 and 61 (now known to be radioactive, non-naturally-occurring, technetium and promethium, respectively).

	Henry Moseley - Wikipedia, the free encyclopedia
		Moseley was born in Weymouth,on the south west coast of England in 1887.
		Moseley's experiments were able to show directly that cobalt and nickel have clearly differing atomic numbers of 27 and 28, and are correctly placed in the periodic table by an objective measure.
		Moseley was also able to order and argue for the separate existence of each of the 14 (no more and no less) lanthanide series of rare-earth elements following lanthanum-- an issue very far from being settled chemically by the science of that time.

	Henry Gwyn Jeffreys Moseley Biography \| World of Chemistry
		Henry Gwyn Jeffreys Moseley's great contribution to science was his ordering of the elements by examining their X-ray spectra, thus creating the periodic table.
		Henry Gwyn Jeffreys Moseley (widely known as "Harry") was born on November 23, 1887, at Weymouth, England.
		Moseley saw that when X rays are beamed at certain crystalline materials, they are diffracted by atoms within the crystals, forming a continuous spectrum on which is superimposed a series of bright lines.

	Moseley, Henry Gwyn Jeffreys - Hutchinson encyclopedia article about Moseley, Henry Gwyn Jeffreys
		From 1913 to 1914 he established the series of atomic numbers (reflecting the charges of the nuclei of different elements) that led to the revision of Russian chemist Dmitri Mendeleyev's periodic table of the elements.
		Moseley was born in Weymouth, Dorset, and studied at Oxford.
		Moseley was killed during the Gallipoli campaign of World War I. In 1913 Moseley introduced X-ray spectroscopy and found that the X-ray spectra of the elements were similar but the frequencies of corresponding lines changed regularly through the series of elements.

	energy and matter aim 1
		Moseley, Henry Gwyn Jeffreys (1887-1915) was a British physicist who first established the atomic numbers of the elements by studying their X-ray spectra.
		Moseley found that when the elements are arranged in the periodic table according to their atomic numbers, all irregularity caused in the older system of grouping elements by their atomic weight disappeared.
		Moseley's fundamental discovery was a milestone in our knowledge of the constitution of the atom, and we are left to ponder on what this great brain might have discovered had he not been so tragically killed at so young an age.

	Moseley, Henry
		Henry Moseley's research career lasted only forty months before tragically ending with his death on a Gallipoli battlefield in World War I. But in his classic study of the x-ray spectra of elements, he established the truly scientific basis of the Periodic Table by arranging chemical elements in the order of their atomic numbers.
		Henry Gwyn Jeffreys Moseley, who was always called "Harry" by his family, was born in Weymouth, England, on November 23, 1887.
		Moseley returned to Oxford, and despite the experimental deficiencies of his laboratories, measured the x-ray spectral lines of nearly all the elements from aluminum to gold.

		These ordinal numbers are the atomic numbers; Moseley concluded that the atomic number is equal to the charge on the nucleus.
		When the elements are arranged according to their atomic numbers the sequence, although almost the same as Mendeleev's arrangement in order of increasing atomic weight, differs slightly; these differences account for the few discrepancies inherent in the Mendeleev system (see periodic law).

		Moseley devised an apparatus for bombarding samples of all the then available elements from aluminium to gold with electrons and measuring the wavelengths, and hence the frequencies, of the K and L lines in their spectra.
		At the time there was no explanation for these multiple lines (and several other weaker lines not shown on Moseley's diagram) and this had to await the discovery of the spin of the electron and the quantum theory, as did the slight departures from linearity.

	Henry Moseley
		Henry Moseley (1887-1915): A British chemist who studied under Rutherford and brilliantly developed the application of X-ray spectra to study atomic structure; his discoveries resulted in a more accurate positioning of elements in the Periodic Table by closer determination of atomic numbers.
		In 1913, almost fifty years after Mendeleev, Henry Moseley published the results of his measurements of the wavelengths of the X-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the X-ray emissions of the elements coincided with the ordering of the elements by atomic number.
		Because of Moseley's work, the modern periodic table is based on the atomic numbers of the elements.

		Henry Gwyn Jeffreys Moseley was born on November 23, 1887 and would die in battle on August 10, 1915, before he turned 28.
		Moseley showed that the correct ordering of the periodic table is on the basis of the atomic number (the number of positive charges in the nucleus).
		It would be Moseley that finally gave the correct answer to why the elements were reversed from a strict ordering based on atomic weights.

		Previous to this, atomic numbers had been thought of as an arbitrary number, based on sequence of atomic weights, but altered when necessary (for example, by Dmitry Ivanovich Mendeleev) to put an element in the appropriate place in the periodic table.
		Only twenty-seven years old at death, Moseley could in many scientists' opinions have contributed much to the knowledge of atomic structure had he lived a bit longer.

		Moseley discovered a strict relationship between the x-ray diffraction spectra of elements, and their correct location in the periodic table.
		It was later shown that the atomic number corresponds to the electric charge of the nucleus — in other words the number of protons.
