Let’s Build It! HW
1. Describe the shape of each of the following molecules. (Use Lewis dot structures, the
periodic table, and HONC 1234 to assist you.)
Cl2
CO2
H2O
H2 S
SO2
2. Which of the above molecules have the same shape?
3. What shape or shapes do you predict for a molecule with two atoms? A molecule with
three atoms? Four atoms? Five atoms? You can draw Lewis dot structures or electron
domains to assist you in answering the questions.
4. Draw a picture of what you think a three-dimensional molecule might really look like if we
could see it. Remember, we can’t see molecules first-hand because they are so tiny so
there is no absolutely correct answer. You can draw water if you wish to draw a simpler
molecule, or you can draw a large molecule like citronellol. Extra credit for creativity and
effort.
