Understand the definition of a compound: A compound is a substance formed when two or more different elements chemically bond together in fixed proportions.
Identify the substances given: Water (H\_2O), Oxygen (O\_2), Gold (Au), and Hydrogen (H\_2).
Analyze each substance: Oxygen and Hydrogen are diatomic molecules consisting of only one type of element, so they are elements, not compounds.
Gold is a pure element, consisting of only one type of atom, so it is not a compound.
Water consists of hydrogen and oxygen atoms chemically bonded in a fixed ratio (2 hydrogen atoms to 1 oxygen atom), making it a compound.
