Answers to Review Questions
... 1. Do all atoms of an element have the same atomic number? The same atomic mass? Explain. Atomic number is based on the number of protons, hence all atoms of a particular element have the same atomic number. Isotopes vary in the number of neutrons, hence a different atomic mass. 2. How many atoms wo ...
