The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. It defines the element’s identity; for example, hydrogen has Z = 1, helium has Z = 2, and so on. Because atoms are electrically neutral (in their standard state), the atomic number also indicates the number of electrons surrounding the nucleus. Differences in atomic number lead to different chemical properties and placement on the periodic table.
