The number of protons and neutrons with the help of the symbol of nuclide are to be determined. Concept Introduction: To understand the radioactivity of heavy elements, the symbol for radioactive elements are used. The notation of elements is written as Z A X . X is the chemical symbol of the isotope. A is the mass number of the isotope. Z is the atomic number of the isotope. The atomic number and proton number in the element are the same. Atomic mass of the isotope is calculated by the sum of neutrons and protons present in the nucleus.
