An element has one individual type of atom. Then a compound is when you have two or more elements combined chemically.
Today we used a piece of solid magnesium and heated it over a Bunsen burner.
After about ten seconds the magnesium turned into magnesium oxide.
The magnesium oxide looked white and had a colourless gas.
It turned into a different solid, which was a powder.
Once this process was done it could not be reversed.

Mg + O2 -> MgO
Magnesium + Oxygen -> Magnesium Oxide
