Which of the following elements is most similar to Fluorine?
a. Oxygen
b.Chlorine
c. Argon
d. Neon
b. Chlorine- because it is in the same GROUP as Fluorine, it has the most similar physical and chemical properties.

Mixtures can be broken down into two types. What are they, and what is the difference between them?
Heterogeneous- when a mixture is not evenly mixed, and you can see the difference between the different parts (such as trail mix)
Homogeneous- when a mixture is evenly mixed, so you can not see the different parts (such as salt water)

What is the difference between mass and volume?
Mass is the amount of matter in an object.
Volume is the amount of space an object takes up.
