Work Step by Step

This question deals with determining which figures show a pure compound. A pure compound is a substance made up of two or more different elements, that is they contain two or more different types of atoms. For it to be a pure compound, the same compound would have to be present throughout the entire figure, meaning you would have the same multiple elements in the same configuration throughout the figure. The only figure for which this applies is figure iv. The answer is iv.
