Hmmm... Water? It's not an element. it's made of two so it's bi and not compound. It's not pure because it disperse and evaporates under heat. Pure substances are more like metals
• 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. Anytime you see a chemical formula with more than one element symbol in it, it’s an element non example.

• The most popular non examples of a compound are gold, silver , and bronze.

• A pure element or compound contains only one substance, with no other substances mixed in. Inpure materials may be mixtures of elements, mixtures of compounds, or mixtures of elements and compounds.
