Composition of the nuclei of two atomic species X and Y are given as under X: Protons (6), Neutrons (6) Y: Protons (6), Neutrons (8) Give the mass numbers of X and Y. What is the relation between the two species?

Answers (1)

As we know,

the mass number of an atom = No. of protons + No. of Neutrons

So,

  The mass number of X = No. of protons of X  + No. of Neutrons of X

                                       = 6 + 6

                                       = 12

  The mass number of Y = No. of protons of Y  + No. of Neutrons of Y 

                                       = 6 + 8

                                       = 14

As both X and Y have the same atomic number (6) but different numbers (i.e., 12 and 14 respectively),  they are isotopes.
