Mass Number and Number of Neutrons

What is the mass number of an atom?
Why is it called a "mass number"?
How many nucleons are in an atom of an element?
How many neutrons will you find in the nucleus of an atom?

These are all good questions, which is why AUS-e-TUTE has just added new resources to help you understand and answer these questions.
AUS-e-TUTE members should log-in to access the new tutorial, game, test and drill.

A "free-to-view" mass number tutorial with worked examples is currently available at

If you want to play the games, do the tests, exams and drills and get immediate feedback on your answers, you will need to join AUS-e-TUTE.
