Mr. Getulio

An atomic number is the number of protons or the positive charge(+) in the atomic nucleus. Which determines the chemical properties of an element for the periodic table and its place in the periodic table also.  Inside an element on top of the element initials there is a number. That number determines what elements the atom is. There is from 1-103 different elements/atom on the periodic table. Only that each atom belong to a different group therefore thats why the periodic table has a lot of different groups to define and know which elements belong to what group number.

In the photo as you can see, the arrows show the meaning of the atom and what is it called. Thats only an example so that you can know and understand better why every box has different numbers and symbols.  In the photos it shows what stands for the name. what stands for the symbol which is easy. what stands for the average mass. and what stands for the electron configuration since you already know what stands for the atomic number.  There are more than just aluminum.
