Question

why do element have fractional atomic masses

​

Answer 1

Answer:

Reason for fractional atomic mass:

The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses. Since the atomic mass of isotopes are different, so average atomic mass is calculated for a single element
