You deserve more than just a letter answer, or else you won't learn what this is about.
Think of water. It is made of oxygen and hydrogen. As elements, these 2 gases have very unique properties. For example, hydrogen is very flammable (it is the fuel used in the space shuttle). Both are gases at room temperature.
Contrast that with water. You can see that the properties of a compound have nothing in common with the properties of the elements that it is made of.
