the charge on each isotope

Answer 1

To calculate the average atomic mass of an element, the correct information needed is:

**the relative abundance of its isotopes**

This information, combined with the masses of the individual isotopes, allows for the average atomic mass calculation. The other options are not necessary for this calculation.
