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 = Protons +
Mass number of X =
Mass number of Y =
As atomic number is equal to number of protons, the atomic number is same, i.e., 6.
Both X and Y are of same element.
