On the Periodic Table of Elements, the order from top left to bottom right is determined by the atomic number of that element, which is determined by the number of protons that are present in the nucleus of that element's atom.
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.
This is called the "Periodic Law" or "Principle of Periodicity".
He had to arrange the elements in a specific sequence to unlock the hidden pattern.
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.
mendelev arranged the elements in the periodic table in the asending order of the mass number of elements.
