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 elements in order of atomic number. Columns in the table - groups. The elements in any one vertical column are said to be in the same group or family. Eight of the groups are numbered from left to right. Elements in the same group have similar chemical properties. The group number is the same as the number of electrons in the outer shell of all the elements in the group.
