Explanation:

An element is a pure substance that cannot be broken down into simpler substances. Oxygen (\(O_2\)) is made up of only oxygen atoms, so it is an element. A compound is a substance formed when two or more different elements chemically combine. Water (\(H_2O\)) is composed of hydrogen and oxygen atoms chemically bonded together, so it is a compound.

Answer:

element; compound
