What is an example of a substance that is made of only one type of atom?

A substance of only one type of atom would be a pure substance from any of the elements in the period table. A common example could be nitrogen, N2, which is easily isolated, or gold, Au, which tends not to form compounds with other elements.

If we consider any real volume of a real material, there will be impurities; small amounts of other elements. On earth, we have been able to refine silicon, Si, to a highly pure state. This may be the best example of a substance of only one type of atom. There may be other better answers such as some parts of a star contain only hydrogen, H, or helium, He.

Explanation:

The answer may depend on how tolerant you are to impurity, and whether you count different isotopes as same or different type of atom.

Many gases, such as Helium, Nitrogen, Oxygen, … would fit the bill. In fact even a mixture of regular oxygen (O2) and ozone (O3) is made only of O atoms, so matches your definition while not being “pure”Many metals that are not alloys: pure gold or silver or copper or iron etc. But beware that steel is by definition not just pure ironPure carbon comes in many variations: (pure) coal, graphite, diamond, and on recent times also as fullerene

In principle, you might simply walk through the periodic table and for each element check if it exists in a pure form …

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
