Give the mass number of x and y what is the relation between the two s

1.	Give the mass number of x and y what is the relation between the two species ?
Answer» Mass number = No. of protons + No. of neutronsSo, Mass number of X = 6 + 6 = 12 Mass number of Y = 6 + 8 = 14Thus, the mass number of X is 12 and that of Y is 14. Now , X contains 6 protons, therefore, the atomic number of X is 6. Y contains 6 protons, therefore, the atomic number of Y is also 6. Since X and Y have the same atomic number (of 6) but different mass numbers (of 12 and 14) , they are a pair of isotopes. Atomic number 6 is of carbon element. So, both X and Y represent carbon element.
