henry moseley

henry gwyn jeffreys moseley known as harry moseley -lrb- 23 november 1887 -- 10 august 1915 -rrb- was an english physicist .
moseley 's outstanding contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number .
this stemmed from his development of moseley 's law in x-ray spectra .
moseley 's law justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a logical order based on their physics .
moseley 's law advanced atomic 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 .
that theory refined ernest rutherford 's and antonius van den broek 's model , which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its -lrb- atomic -rrb- number in the periodic table .
this remains the accepted model today .
when world war i broke out in western europe , moseley left his research work at the university of oxford behind to volunteer for the royal engineers of the british army .
moseley was assigned to the force of british empire soldiers that invaded the region of gallipoli , turkey , in april 1915 , as a telecommunications officer .
moseley was shot and killed during the battle of gallipoli on 10 august 1915 , at the age of 27 .
prominent experts have speculated that moseley could have been awarded the nobel prize in physics in 1916 , had he not been killed .
as a consequence , the british government instituted new policies for eligibility for combat duty .
