    The 4 indicates the sum of the protons and neutrons and electrons present in the atom. The superscript (number on top) shows the atomic mass, the sum of the protons and neutrons and the electrons. The subscript (number on the bottom) shows the atomic number, or the number of protons. All of these numbers are on the left side of the atomic symbol.
