You're asking for examples of substances that are elements. It's important to understand the difference between elements and substances:

* Elements are the simplest pure substances that cannot be broken down further by chemical means. They are made up of only one type of atom.

* Substances are pure materials with a definite composition, which can include elements or compounds.

So, all elements are substances, but not all substances are elements.

Here are some examples of elements (which are also substances):

* Metals: Gold (Au), Silver (Ag), Copper (Cu), Iron (Fe), Aluminum (Al)

* Nonmetals: Oxygen (O), Nitrogen (N), Carbon (C), Sulfur (S), Phosphorus (P)

* Metalloids: Silicon (Si), Germanium (Ge), Arsenic (As)

Let me know if you'd like examples of substances that are *not* elements, like compounds!
