en.wikipedia.org/wiki/Periodic_table

The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their recurring properties. The number of each element corresponds to the number of protons in its nucleus (which is the same as the number of electrons orbiting that nucleus).

The periodic table is an arrangment of the chemical elements ordered by atomic number so that chemical periodic properties of the elements (chemical periodicity) are made clear. There is no one single or best structure for the periodic table but by whatever consensus there is, the standard form used here is very useful and the most common.
