TOPIC 6: CHEMICAL COMPOUNDS
Name: ________________________ 9___
Date: __________
Outcome #3d: distinguish between ionic and molecular compounds, and describe the
properties of some common examples of each
Outcome #4a: read and interpret chemical formulas for compounds of two elements,
and give the IUPAC name and common name of these compounds
Outcome #4b: identify/describe chemicals commonly found in the home, and write
the chemical symbols
Outcome #4c: identify examples of combining ratios/numbers of atoms per molecule
found in some common materials, and use information on ion charges to predict
combining ratios in ionic compounds of two elements
Outcome #4d:
assemble or draw simple models of molecular and ionic compounds
