  Henry Moseley
Henry Moseley (1887-1915): A British chemist, Henry Moseley studied under Rutherford and brilliantly developed the application of X-ray spectra to study atomic structure; Moseley's 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 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 Summary
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
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.

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.

 News from New Orleans Museum of Art
Henry Casselli is a local artist, born in the Ninth Ward, who has enjoyed much success.
Casselli's work is a witness to history: as shown in his work in Vietnam as a combat artist, at NASA, in the White House and after Hurricane Katrina; it is also an intimate recorder of the human condition.
Even in his earliest artistic efforts, New Orleans native Henry Casselli successfully captured the intimate details of the human condition.

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.

 Maynard Moseley Award
MAYNARD MOSELEY was widely recognized for his enthusiasm for and dedication to teaching and his students, as well as for his research using floral and wood anatomy to understand the systematics and evolution of angiosperm taxa, especially waterlilies.
The Maynard F. Moseley Award was established in 1995 to honor a career of dedicated teaching, scholarship, and service to the furtherance of the botanical sciences.
Moseley, known to his students as “Dr. Mo”, died Jan. 16, 2003 in Santa Barbara, CA, where he had been a professor since 1949.

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.
Moseley would have been an obvious candidate for the chair, which was filled in 1919 by the appointment of Lindemann (subsequently Lord Cherwell)...

 Thread 1 - Atomic Weight and Periodic Properties
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.
