Mendeleev’s  Periodic Table ,[object Object],[object Object]
Henry Moseley 1887 - 1915 In 1913, through his work with X-rays, he determined the actual nuclear charge (atomic number) of the elements*.  He rearranged the elements in order of  increasing atomic number. *“There is in the atom a fundamental quantity which increases by regular steps as we pass from each element to the next.  This quantity can only be the charge on the central positive nucleus.”
