Answer:
Mass of atom = Protons + Neutrons
Therefore
6+6=12u
And
6+8=14u

Answer:
this is your answer
Explanation:
Atomic mass of X = Number of protons + Number of neutrons = 6 + 6 = 12. Atomic mass of Y = Number of protons + Number of neutrons = 6 + 8 = 14. These two atomic species, X and Y, have the same atomic number but different mass numbers. Hence, they are isotopes.
