SCH 3U
Chemistry Unit Test Outline
1) I can describe trends in atomic radius, ionic radius, ionization energy, and electronegativity down a
family or across a row on the periodic table and use atomic structure to explain why these trends
exist
2) I can use isotopic abundance to determine the relative atomic mass of an atom
3) I can identify compounds as ionic or molecular
4) I can describe properties of ionic and molecular compounds
5) I know what an electrolyte is and how it forms
6) I can draw Lewis-Dot diagrams for atoms and ions
7) I can draw Lewis Structures for ionic and molecular compounds (use HWSB to determine number
of bonds and lone pairs in molecular compounds). I know the bonding capacities for hydrogen,
carbon, silicon, nitrogen, phosphorous, oxygen, sulfur, and the halogens
8) I can define and give an example of a coordinate covalent bond
9) I can explain how many electrons are shared in single, double, and triple bonds
10) *I can describe the different types of intermolecular forces (London, Dipole-Dipole, and Hydrogen
Bonding) and their relative strengths and use this to predict relative boiling or melting points of
compounds – I know which atoms are attached to hydrogen if hydrogen bonding is possible
11) *I can use electronegativity values to determine whether bonds are polar, non-polar, or ionic and
use the Greek symbol ‘delta’ to show slight positive or slight negative charges on atoms of polar
molecules
12) Based on shape and composition, I can predict whether a molecule will be polar or nonpolar
13) I can explain the idea of “like dissolves like”
14) *I can name (using IUPAC and Classical names) and write formulas for ionic, molecular, polyatomic,
multivalent, hydrate, acid, and base compounds; I understand the per-ate, -ate, -ite, and hypo-ite
naming system for oxyanions
15) *I can explain how structure and composition of molecules contribute to the properties of
common chemicals, with reference to specific molecules discussed in class (artificial sweeteners vs
sugar, DDT, EDTA).
*These topics will be given the most consideration on the unit test
