The given table containing chemical symbol, atomic number , mass number, number of protons and neutrons is to be completed. Concept Introduction: The atomic number of a chemical element constitutes the number of protons present in the nucleus of that particular element. The number of neutrons can be calculated by subtracting the atomic number from the mass number. In one of the cases, the element symbol has to be identified which can be easily found out using the atomic number and mass number through periodic table.
