Answer:
A pattern of repeating order is called periodicity. In the mid-1800s, Dmitri Mendeleev, a Russian chemist, noticed a repeating pattern of chemical properties in elements. Mendeleev arranged the elements in order of increasing atomic mass, to form something that resembles the modern periodic table.
