Study Guide – Atomic Theory
- Describe the basic idea of the Atomic Theory.
- Describe Rutherford’s experiment and his two discoveries.
- List the three subatomic particles, their symbols, their charges, their relative masses, and their location in the atom. (You can make a chart if it’s easier.)
- What is the Atomic Number and its symbol? Why is it so important?
- What is the Mass Number and its symbol?

What does the number represent?
- For the following atom, tell the (a) mass number, (b) atomic number, (c) # protons, (d) # neutrons, and (e) # electrons.
- What is an isotope?
- What is the average atomic mass? Why are the atomic masses on the periodic table written as numbers with long decimals?
- How is the average atomic mass different from the mass number?
- How do you calculate the average atomic mass from the relative abundance?
