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 periodic table is an arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations and recurring chemical properties.Elements are presented in order of increasing atomic number.The standard form of the table consists of a grid of elements, with rows called periods and columns called groups. The history of the periodic table reflects over a century of growth in the understanding of chemical properties.he Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass.
