Considering the defintion of atomic number, the Periodic Table is arranged in order by atomic number.
What is atomic number
All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged (electrons).
The atomic number indicates the number of protons that are present in the nucleus of an atom.
The atomic number allows you to organize the known elements in the Periodic Table, going from the smallest to the largest number of protons in the nucleus as you go through the rows and columns of the table.
So, each chemical element in the periodic table is characterized by having the same number of protons (Z). However, the same chemical element can have different numbers of neutrons.
Summary
In summary, the Periodic Table is arranged in order by atomic number.
