The nucleon number of an atom is defined as the total number of protons and neutrons in its nucleus.

Nucleon number is represented by the symbol A. ? Number of neutrons N in the nucleus :- N = A - Z Nuclide Notatio! n ? The nucleus of an atom with a particular number of protons and neutrons is called a nuclide. A nuclide is reffered to by its nucleon number, for example, atomic number 3 6 and carbon 12. ? Each geek of tom has a symbol. For example, H is the symbol for hydrogen atom. ? If an atom of an element X has a nucleon number A and a proton number Z, its nuclide is repersented by the following notation : Isotopes ?
