Study Guide for Chapter 6 Exam
This is a general guideline of the things you should
know and be able to do in order to be successful on
the chapter 6 test. It is important, not only to study,
but to study wisely! Study the skills and concepts
that you are struggling with and make sure to
practice the skills you must demonstrate….practice
drawing Lewis structures, predicting molecular
geometry, etc. As always, all vocab that we have
learned from the chapter could be on the test, so
make sure you know the terminology.
6.1 Be able to:
 Explain what a chemical bond is and why most
atoms form chemical bonds (octet rule)
 Describe ionic and covalent bonding. Explain
how they are similar and why most bonds are
not purely covalent or purely ionic.
 Classify bonding type according to differences in
6.2 Be able to:
 Explain the relationship between bond length
and bond strength. Understand the relationship
between distance between approaching atoms
and bond length.
 State/explain the octet
 Be able to explain and apply the Lewis structure
in order to demonstrate how atoms bond to one
another to form molecules.
 Demonstrate and explain resonance structures.
6.3 Be able to:
 Compare and contrast the chemical formula for
a molecular (covalent) compound and an ionic
 Explain the arrangement of ions in crystals.
 Explain lattice energy.
 Write the Lewis structure of a polyatomic ion.
Make sure to use [ ]+/- only when dealing with
polyatomic ions.
6.4 Be able to explain metallic bonding and explain
why metals have characteristic properties such as
malleability, ductility, conductivity, and why they
are shiny due to metallic bonding.
6.5 Be able to:
 Explain the VSEPR Theory and apply this theory
to predict shapes of molecules and polyatomic
 Describe dipole-dipole forces, Hydrogen bonds,
and London Dispersion Forces (LDF) and how
(Boiling point, melting point,
 Explain what determines molecular geometry
and be able to predict the polarity of a molecule
based on the molecular geometry.
