The atomic number on the periodic table (or anywhere else) tells  you which element is being specified. The atomic number of an atom  is the number of protons in the nucleus â¦ of that atom, and it is the  elemental identity of that atom. Only the number of protons  identifies an element.
The reason the periodic table is the shape that it is has to do with the electronic configurations of the elements. The periodic table is arranged so that all the elements in each period (row) have similar electronic configurations to the other elements in that period. That also often means that elements in the same group (column) show similar chemical reactivity. Electrons in atoms are arranged in different orbitals (named s, p, d, and âf).
