He had to arrange the elements in a specific sequence to unlock the hidden pattern.
On the periodic table, the elements are arranged by Atomic Mass. Helium and Hydrgen are at the way top of the table due to how they have the smallest amount of mass. The elements with the biggest mass are at the bottom.
Scientists arrange elements into metals, nonmetals, and metalloids based on their physical and chemical properties. Metals are typically good conductors of electricity, nonmetals are poor conductors, and metalloids have properties of both metals and nonmetals.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
