Small Radioactive seal source Cesium 137 in the Plastic package · A stylized Cesium atom visualization, with the number of protons, neutrons, electrons and.

This nucleus has 56 protons and 137-56=81 neutrons. Two numbers are used to identify a nucleus: Atomic number -- number of just protons in the nucleus. The atomic number determines what an element is chemically, for the number of protons determines the number of electrons needed to balance the charges in an atom, which in turn determines the electron configuration the atom will adopt.
