How did moseley rearrange the elements
WebMoseley hypothesized that the placement of each element in his series corresponded to its atomic number Z, which is the number of positive charges (protons) in its nucleus. Argon, for example, although having an atomic mass greater than that of potassium (39.9 amu versus 39.1 amu, respectively), was placed before potassium in the periodic table.

In 1869, Dmitri Mendeleev and Lothar Meyer individually came up with their own periodic law "when the elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically." Meyer based his laws on the atomic volume (the atomic mass of an element divided by the density of its … WebMoseley helped make advancements in atomic, quantum and nuclear physics. He helped refine the periodic table created by Rutherford and demonstrated that elements listed in the periodic table should be determined by their atomic numbers rather than their mass.
