Element. They are all the same. Example of this would be any metal in the solid state (iron, cobalt, etc).
Element. They are all the same. Example of this would be any diatomic element (H2, Cl2 are two.)
Compound. At least two different elements joined together into one unit (a molecule in this case).
Element. They are all the same. Example of this would be any monotomic element in the gaseous state. At room temperature, elements like Rn of He. At high temperature, you could have something like sodium vapor of copper vapor.
