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

Mass number of X = No. of protons + No. of neutrons
= 6 + 6 = 12
Mass number of Y = 6 + 8 = 14
The species X and Y are isotopes because their atomic numbers are same and their mass numbers are different i.e., \(_{6}^{12}{C}\) and \(_{6}^{14}{C}\)
