In 1803, the English school teacher and part-time scientist, John Dalton published his first list of elements when he printed his atomic theory and his early gas law work. He was the first person to recognise the periodic trends in the properties of elements, and the graph shows the pattern he saw in the atomic volume of an element plotted against its atomic weight. Dimitri Mendeleev made the first-ever periodic table, but it had errors and was not up to the mark; Moseley researched and fixed the original mistakes. 29 Dec. 2014. Moseley's Periodic Table.
