Product Description

When Bonds Break

Story:

A woman is found dead in her apartment and all signs point to accidental carbon monoxide poisoning. But is the case really that simple? Students solve the case while learning about ionic, covalent, and metallic bonds.

Note: This product is also part of a BUNDLE found here.

Objectives:

1. Name ionic compounds containing main group or transition metals, covalent compounds, acids and bases using IUPAC nomenclature rules.

2. Write chemical formulas of common polyatomic ions, ionic compounds containing main group or transition metals, covalent compounds, acids, and bases.

3. Construct electron dot formulas to illustrate ionic and covalent bonds.

4. Describe the nature of metal bonding and apply the theory to explain metallic properties such as thermal and electrical conductivity, malleability, and ductility.

5. Predict molecular structure for molecules with linear, trigonal planar, or tetrahedral electron pair geometries using VSEPR theory.

6. Compare the reactivities of metals and use an activity series to predict the products of a reaction.

Components:

Product is split into student pages and teacher pages. Teacher instructions and keys are provided in the teacher pages.
