The Periodic Table was first arranged by Dmitri Mendeleev in 1869 based on Atomic Mass and the properties of elements. Later, elements were restructured by Henry Moseley in 1913, who proposed organizing them by atomic number instead of atomic mass. Other scientists, including Glenn T. Seaborg, contributed by discovering and isolating new elements, which led to the modern layout of the table.
