
Skim pages 20-23 in your textbook. Be
prepared to answer questions about the
concepts discussed on those pages.


A chemical bond represents chemical energy
and is a force that holds atoms or molecules
together.
What is the difference between a compound
and a molecule? Draw and example of each in
your notes.
Relate the terms ion, ionic bond, and salt.
Compare the contrast ionic and covalent
bonding.


One covalent bond represents the sharing of
2 electrons.
Covalent molecules can have multiple bonds.
Write a sample compound with a single,
double, and triple bond.
 Double covalent bonds are more reactive than
single covalent bonds.



Why is the shape of a molecule important?
What determines the shape of a molecule?
Linear vs Bent vs Tetrahedral shapes



Define electronegativity.
Contrast nonpolar and polar covalent bonds
Define hydrogen bond.
 Why is a hydrogen bond important to the structure
and function of a molecule?
 Each hydrogen bond is weak, but a large number of
hydrogen bonds is strong.
 Examine Figure 2.9 with the different representations
of a water molecule.

Covalent and ionic bonds hold atoms together,
while hydrogen bonds hold molecules together.

List the six properties of water in your notes
with a couple of spaces in-between each.
 Define and provide an example of each property
in your notes.

Review acids (H+) and bases (OH-)
 Discuss pH and concentration
 What is a buffer?
 Regulation of pH by buffers is essential to all living
systems.
