periodic law: when the elements are arranged in order of increasing atomic number, their properties repeat in regular intervals (periods). Henry Moseley: (1913) rearranged the elements by increasing nuclear charge (atomic number) instead of atomic mass. This fixed the exceptions in Mendeleev’s table.
