It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Po-210 (Polonium, atomic number Z = 84, mass number A = 210). Landolt-Brnstein Homepage Introduction Index...
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A radioactive isotope is one that breaks apart and gives off some form of radiation. About the only isotope of any use is polonium-210. ...
