Answer:
Element non examples include all compounds, which are substances made when two different types of atoms form a chemical bond. Any material made by mixing elements is no longer an element.

The option which is not an example of an element from the given options is option 3: Water.
- Element is a chemical substance that is in its purest form, containing only one kind of atom. It does not contain with it, any other atom.
- Water is not an element, rather it is a molecule. A water molecule contains two atoms of hydrogen and one atom of oxygen, formed through chemical hydrogen bonding. It does not exist as a single atom in its pure state alone.
- Oxygen, gold, and hydrogen are the elements because they are the pure form containing only one type of atom.
- Hence, water is the correct answer here.
