Are the atomic masses of some elements actually fractional ?

Text Solution

Verified by Experts

No, the actual masses are not fractional. It is the average of the atomic masses of the isotopes of an element which maybe fractional. For example, the two isotopes of chlorine have atomic masses 35u and 37u respectively. The average atomic mass of chlorine is 35.5 u.
