Minerals, Alloys, and Compounds (471)

This collection contains samples that are not pure elements, but rather mixtures of several. Most are naturally occurring minerals in more or less the form they come out of the ground. (With a few exceptions, minerals are complex chemical compounds or mixtures of compounds). Other samples here are pure chemical compounds or alloys (mixtures of metals). Each sample is listed under all of the elements it contains.

Click any element tile below to get the full entry for that element, or click on the sample picture to go directly to the description of that sample.
