The atomic number is the number of protons in an atom's nucleus.[1] (It is also the number of electrons surrounding the nucleus, if the atom is electrically neutral.) In many representations of the Periodic Table of the Elements this number is placed either above the element's symbol or in the upper right hand corner.
