
What makes up most of the atom? (#10 Atomic Models)
What are some inaccurate aspects of our diagrams of atoms and molecules? (#10 Atomic
Models)


How did Thomson, Rutherford, and Bohr view the atom? (History of Atomic Theory)
Which person is responsible for: (History of Atomic Theory)
o Creating the idea of the atom
o Formulating our modern version of atomic theory
o Discovering the electron
o Describing electrons as having “levels”
What experiment is Rutherford famous for? What did it prove? (History of Atomic Theory)
Note: Heisenberg will not be on the test


Skills: Things you should be able to do

Draw a diagram of the atom that includes the location of the three types of particles and the
two areas (#6 Structure of the Atom)
o Conversely, be able to identify the correct model of an atom given several choices

Identify the atomic number, atomic mass, and symbol on the periodic table (#7 Reading the
Periodic Table)
Calculate the amount of each of the types of particles in an atom with information from the
periodic table (#7 Reading the Periodic Table)
o This information is on the slide, “What isn’t there…” which I did not make notes (but in
retrospect should have). We have practiced it repeatedly in class, however.


Differentiate between a diagram of nuclear fission and fusion (#8 Fission and Fusion)



Given a molecule formula be able to: (#9 Molecules)
o Count the number of total atoms it represents
o Count the number of types of atoms it represents
Identify an example formula or model as representing either an atom or molecule (#9
Molecules)
Draw or match a molecule with a given formula (#9 Molecules)
o Note: Students will be graded on whether their drawing represents the correct number
of atoms. It will not be graded on the correct order of bonds in the molecule.

Describe the accuracies and inaccuracies of a given model (#10 Atomic Models)

Match Thomson, Rutherford, and Bohr with a description or diagram of their model of the atom
(History of Atomic Theory)
Recommendations on Studying:

Watch carefully for when the terms “particle”, “atom”, and “molecule” are used. Recognizing
which one is being asked about is often the key to the question.

Much of the information on this test is there only to support the skills. For instance, knowing
the charges of the particles is more likely to be tested as a skills-based question (“If you have 5
protons and 4 neutrons, what is the total charge?) than being asked directly (“What is the
charge of the proton?”).

Don’t get bogged down in the history of the atom; there was far more information discussed
than students are responsible for. Focus on the few points suggested above.
