WebIn 1913, the physicist Henry Moseley, working in Manchester and later Oxford, discovered an experimental method for ordering the elements according to their atomic numbers. Prior to this work the elements in the periodic table had been ordered by using their atomic weights, which gave rise to a series with uneven gaps between each element. WebThe periodic table can often be presented with an abundance of data about each and every element listed. In it's simplest form (shown below), each entry only has three pieces of information that you will need to know. These three pieces of data are the elemental symbol, the atomic number (typically given the symbol, Z, and the atomic weight.
