Question

GIVE THE MASS OF X AND Y. MENTION THE RELATIONSHIP BETWEEN THE TWO ATOMS​

Answer 1

Answer:

Mass number of X = Number of protons + Number of neutrons = 6 + 6 = 12. Mass number 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.
