This intrigued Moseley, who wondered if he could study these X-rays to learn more about what goes on inside atoms; he had van den Broeks hypothesis in mind specifically. It has a unique arrangement of rows and columns. The table below shows the example of Gallium, which Mendeleev called eka-aluminium, because it was the element after aluminium. Difference Between Mendeleev and Modern Periodic Table The periodic table is a way of organising the elements which is used by scientists to group elements with similar properties. As a consequence, the British government instituted new The metals are placed on the left and the non-metals are placed on the right. He worked as a telecommunication officer until he died during the Battle of Gallipoli in 1915. A year later he was dead, felled by a snipers bullet in WW1. 3 Moseleys work showed that, in 1913, only four elements remained to be discovered that had lower atomic numbers than uranium.

In 18 hectic months, physicist Henry Moseley revealed the structure of the atom, and the basis of chemistry. As we have seen, Mendeleev was not the first to attempt to find order within the elements, but it is his attempt that was so successful that it now forms the basis of the modern periodic table. In 1911 Antonius van den Broek had published his hypothesis that atomic number which at this time was simply the position of an element in the periodic table might actually be equal to the amount of charge in the atoms nucleus. This stemmed from his development of Moseley's law in X-ray spectra. He worked as a telecommunication officer until he died during the Battle of Gallipoli in 1915.

In 1913 he used self-built equipment to prove that every elements identity is uniquely determined by the number of protons it has. He even predicted the properties of five of these elements and their compounds. In 1914 Rutherford and Bragg recommended to the University of Oxford that Moseley should be appointed to a chair of physics that was becoming vacant there. This 1868 table listed the elements in order of atomic weight, with elements with the same valency arranged in vertical lines, strikingly similar to Mendeleevs table.
