We just learned about the chemical element of Oxygen.
Another chemical element is Sulfur, called "S" for short on the Periodic Table.
Sulfur is a chemical found on our planet that has many uses.
It burns very well, so the chemical on the end of a match stick is sulfur.
Sulfur is also very smelly, and smells like rotten eggs. It is the smell in skunk spray that makes it so bad!
