Mrs. M. Hutchins “A” Honors
Chemical Bonding Hot List A Chapter
8 March 2006
View the sites below and answer the questions that follow
A. Chemical Bonding
- Read Introduction.
What did Lewis observe about atoms and what did he suggest?
- Read Ionic
Bonding. Explain in your own words the nature of an ionic bond.
on the Simulation of the reaction of NaCl.
There are three pages. Click on the prompt at the bottom right to go to
page 2 and 3.
Explain what you see.
reading about ionic bonding. Explain why there is no such thing as
a single ionic molecule.
- Read Covalent
Bonding. Click on the covalent
bonding simulation and explain what you see.
reading Covalent Bonding. Explain why ionic “molecules” do not
exist but covalent molecules do.
- Read Multiple
Bonds And Lewis Dot Structures. From
your notes or text what other type of multiple covalent bond exists? Draw
the Lewis dot structure of three molecular compounds- One with
single bond(s), One with double bond(s) and one with triple bond(s). Make
statements about bond length and bond strength related to the number of
bonds between atoms.
- Read Polar
and Nonpolar Covalent Bonding. Click on the simulation
of the water molecule. Explain what you see.
9. From your notes explain electronegativity
of atoms and how polar covalent bonds are formed. Draw and example of a molecule with nonpolar covalent bond(s) and one with polar covalent bond(s)
indicating electronegativities of each atom,
differences in electronegativities and partial
charges if present.
10. Read Dipole. Explain the nature of a dipole. Go
back to the previous simulation and explain why water is a dipole.
Bonding: polar covalence
