Binding energy is also stated as the amount of energy released when a nucleon is disassembled from the nucleus. The difference in the binding energy between the initial nucleus and the end product of nuclear reaction constitutes nuclear energy. The binding energy of the nucleon is much greater than the electrical forces present in between the electrons. Binding energy is specific for different nuclei. The minimum energy by which the nucleus of an atom is divided into constituent protons and neutrons is called the binding energy. The atomic number is 6.Ī strong nuclear force binds the nuclei of an atom. The mass number is independent of electrons as its mass is negligible.įigure 1 Representation of atomic number, chemical symbol, and mass number of isotopes of CarbonĪs shown in the above figure, Carbon C has two stable isotopes having mass numbers 12 and 13. The sum of protons and neutrons gives the mass number of an atom. Elements having the same number of protons and a different number of neutrons are called isotopes. Elements can have the same number of protons but not the same number of neutrons. The atomic number of an element is the number of protons present in the nucleus of an atom and it differentiates one element from another. Protons and neutrons are together called nucleons. Electrically positive charges are protons, neutrons are electrically neutral. The nucleus of an atom consists of a proton, neutron. Atomic structure: An atom consists of electrons revolving around the nucleus which is present at the center.
