Early versions of the periodic table were less than exact in their placement of elements. Experts have speculated that Moseley could have been awarded the Nobel Prize in Physics in 1916, if he had not been killed. B.different #'s of protons Dmitri Mendeleev | Biography, Periodic Table, & Facts Moseley enlisted in the army when World War I broke out in 1914. He experimented with the wavelengths of certain metals that emitted x-rays, and he calculated the positive charges present in the nucleus of an atom. In 1914 Moseley published a paper in which he concluded that the atomic number is the number of positive charges in the atomic nucleus. 1913 was a year of highs and lows in physical sciences. He showed that in each triad the mean of the lightest and heaviest atomic weights approximated the atomic weight of the middle element. Moseley is the scientist most directly responsible for realizing that the structure of the atom is key to understanding the elements themselves. Urbain was also keen to collaborate with Moseley, and in June 1914, he traveled to Oxford with several samples, celtium included.
