What is the difference between a molecule and a compound?

• A molecule can be made of same or different elements. Compounds must be made of different elements.

• A molecule can only be made of the same element but a compound can have two of the same element.

• A molecule can be seen with the eyes but a compound must be seen using a microscope.

• Molecules are much cooler than compounds. Isn't that why we call them mole-cools?

Why did some marshmallows have two toothpicks between them while others only had one?

• The two toothpicks represent a double bond.

• The two toothpicks represent shared space.

• Two toothpicks were needed to secure some marshmallows that weren't sticking together enough.

• The two toothpicks represent the second orbital.

In the Mixtures section, why didn't you connect the water and the salt with a toothpick?

• Because the salt and water are not bonded together.

• Because the salt is more dense than the water.

• Because the salt and the water have a double bond.

• Because the salt is a molecule while the water is a compound.
