1. I know the properties of the parts of an atom.
2. I can explain that the strong nuclear force holds the nucleus together.
3. I can explain that the attraction between opposite charges holds an atom.
4. I know that the number of protons identifies the element by the atomic number.
5. I know that the atomic mass equals the number of protons and neutrons.
6. I can explain that isotopes have a different number of neutrons.
7. I can explain that the average atomic mass accounts for isotopes.
8. I can tell that positives charges from protons and negative charges from electrons cancel each other out.
9. I can explain that ions are formed when atoms gain or lose electrons.
10. I can draw and interpret the Bohr model of the atom.
11. I can understand the modern 'cloud' model of the atom.
12. I can explain how atomic theory has changed over time.
13. I can name at least 4 scientists and their contributions to the modern atomic theory.
