Lesson 7
... Mass Number: The mass of an atom consists of the contents of its nucleus – protons and neutrons. Once you know the mass number, you can also determine the number of neutrons. Isotopes: Atoms with the same number of protons but different numbers of neutrons. (ex. Lithium isotope with a mass number of ...
