Chapter 4 and 5 -You Should Know
For
this test you should be familiar with the following concepts and tasks:
1.
Differentiate
between atoms, ions, and molecules
Knowledge of
the three subatomic particles, their properties and their location within the
atom.
Define and
give examples: ionic bonding – (metal
and non-metal), covalent bonding
–(non-metal and non-metal) –explain how different ions form bonds
Draw and
interpret Bohr models for first 20 elements on the periodic table
Identify
valence electrons using the periodic table
Draw and
interpret Lewis diagrams showing bonds for ionic compounds (eg NaCl. MgO) and
covalent compounds (eg H2O, CH4)
Distinguish
between lone pairs and bonding pairs of electrons and molecules
2.
Classify
substances as acids, bases, or salts, based on their
characteristics, name and formula
Identify
acids and bases using indicators (chart in the provincial package)
Explain the
significance of the pH scale
Differentiate
between acids, bases and salts with respect to chemical formulas and properties
Use the
periodic table and a list of ions (including polyatomic ions) to name and write
chemical formulas for common ionic compounds
Convert
names to formulas and formulas to names for covalent compounds
3.
Distinguish
between organic and inorganic compounds
Define organic compounds and inorganic compounds
Distinguish
between organic and inorganic compounds based on their chemical structure
Recognize a
compound as organic or inorganic from its name, from its formula or from a
diagram or model
4.
Analyze
chemical reactions
Define and
explain the law of conservation of mass
Write and
balance (using lowest whole number coefficients) chemical equations from
formulae, word equations or descriptions
