Henry Moseley. English physicist Henry Moseley, who arranged the Periodic Table in order of the atomic numbers of the elements. 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.
Henry Moseley created the modern periodic table by putting the elements in order by atomic number. Dmitri Mendeleev made the first periodic table that could successfully predi â¦ ct future elements, but ordered his elements by atomic mass, which we do not do today.endeleev first created the periodic table in 1869.  He thought that the elements must be organised in some way, that we would be able to use for experiments. And he first t â¦ hought of the periodic table. He tried and tried but could not get them all to fit.
