Elements on the Periodic Table are organized by increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement creates groups and periods that share similar chemical properties. Additionally, the elements are also organized by their atomic mass, with elements in each group having similar mass.

Yes, I'm sure. The Periodic Table is arranged in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This organization allows elements to be grouped based on their similar chemical properties. Atomic mass does play a role in the organization of the elements on the Periodic Table, but the primary method of arranging them is by atomic number.
