Understand that the periodic table is a systematic arrangement of elements based on their atomic structure.
Recall that the atomic number of an element is the number of protons in its nucleus, which uniquely identifies each element.
Recognize that the periodic table is primarily arranged in order of increasing atomic number, not by the number of neutrons or atomic mass.
Note that arranging by atomic number ensures elements with similar chemical properties fall into the same groups or columns.
Conclude that the correct way elements are arranged on the periodic table is by increasing atomic number.
