how are isotopes defined unit test quizlet

One isotope of carbon (C) has exactly the same mass number and atomic mass since it was used as the definition of the atomic mass unit (amu). Like unit 1, most of this unit is theory and concept related, so vocab is a big part, especially knowing the names of geometries and types of bonds.
