FALL FINAL EXAM REVIEW
Period _____ Exam Date _________
1. List the SI base units, their symbol, and abbreviation.
2. Convert 3 different SI units from centi- to kilo, and then from Kilo to Base Units.
3. Give the formula and units of measurement for density. The density of Aluminum is 2.7
g/mL, practice determining how many grams it would take to make have x amount of
volume and also how much volume a certain amount of grams would take up.
4. Scientific Notation: Make 5 practice problems changing from Scientific to Standard
notation, make 5 more going the other direction (use 10 to the negative power as well)
5. Practice converting using dimensional analysis. For instance, Turn x amount of seconds into
years or days, and go the other direction as well. Also, practice problems where identical units
and different units are being multiplied together.
6. What are significant figures? Write the rules.
7. Practice at least 2 problems each adding/subtracting and multiplying/dividing using the
rules for sig figs.
8. On a periodic chart, what do we call the elements found in a:
a. horizontal row b. vertical columns 9. Where is the boundary between metals & nonmetals?
10. List the 3 subatomic particles; give the charge for each, and the location of each particle
within the atom.

11. Explain why an atom is electrically neutral.
12. What is an isotope and how are they designated?
13. What is the importance of atomic numbers of elements?
14. Practice writing Nuclear Symbols. Review how to determine how many protons, neutrons, and
electrons there are using a Nuclear Symbol.
15. List the 4 sublevels (orbitals)
16. How many sublevels would the energy level represented by n = 4 be broken up into?
17. How many orbitals does a p sublevel contain?
18. How many total electrons can the second energy level hold?
19. Explain the following, which determine electron configuration:
a. Hund's rule b. Aufbau principle c. Pauli exclusion principle –
20. Practice writing electron configurations for at least 5-10 random atoms on the periodic
table. Don’t be afraid to go to the f- block or past it.
21. What are valence electrons and in what sublevels are the present?
22. Elements in the same group or family have what common property?
23. What is meant by the period of an element?
24. List the family or names of all the elements and identify the most reactive group.

a. atomic radii in a family & a period:
b. ionic radii in a family & period:
c. Ionization energy in a family & period:
d. Electronegativity in a family & period
27. What is a chemical bond and what are the distinguishing features of a(an):
a. ionic bond b. covalent bond 28. What is an ionic formula?
29. What is a molecular formula?
30. List the Greek prefixes for 1-10.
31. Understand chemical formula notation and the use and meaning of subscripts
Be able to write properly balanced chemical formulas using the ion-charge method, always placing
the positive (cation) first in the formula.
32. Describe the rules for naming compounds
-metal / non-metal compounds
3
-transition metal / non-metal compounds
-metal /polyatomic ion compounds
-non-metal / non-metal compounds
33. How do you determine main group element ionic charges from their periodic table groups?
34. Define Binary acids and Oxyacids.
Binary Acids –
-add the prefix ________ and the suffix _____
Oxyacids –
-for polyatomic ions which end in ‘ate’; change the ending to ______ and add acid.
-for polyatomic ions which end in ‘ite’; change the ending to _______ and add acid.
35. Practice writing at least 20 formulas given the name of compounds, and writing 20 names
given the correct formulas. Have someone else make the formulas/ names for you to do.
36. Practice writing Lewis Structures, and identifying the electron domain geometry,
molecular geometry, intermolecular forces, bond angles, and the hybridization for as
many molecules as possible. (largest portion of final is over molecular geometry)
