From the above table we can see that the ratio of their atomic masses is 2. But it is not exactly 2. Why is it so ? Explain.

Text Solution

Verified by Experts

Because the mass of a nucleus is slightly less than the mass of the constituent nucleons. (Actual atomic mass is different from mass number)
