Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?
products |
|
reactants |
|
isotopes |
|
ions |

This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.
