Verified step by step guidance1
Understand that the periodic table is a systematic arrangement of elements based on a specific property that increases as you move from left to right and top to bottom.
Recall that the atomic number represents the number of protons in the nucleus of an atom, which uniquely identifies each element.
Recognize that the periodic table is organized in order of increasing atomic number, not atomic mass or other properties.
Note that atomic mass can vary due to isotopes, and the number of neutrons or isotopes is not the organizing principle of the periodic table.
Conclude that the correct property by which the periodic table is arranged is the atomic number.
