Verified step by step guidance1
Understand that the periodic table is a systematic arrangement of elements based on their atomic structure.
Recall that each element is defined by its atomic number, which is the number of protons in its nucleus.
Recognize that the modern periodic table arranges elements in order of increasing atomic number, not atomic mass or neutron number.
Note that this arrangement reflects periodic trends in chemical properties because elements with similar properties appear in the same columns (groups).
Conclude that the correct way elements are arranged in the current periodic table is by increasing atomic number.
