Native element minerals

This episode, "Native Element Minerals," explores a fascinating class of minerals composed of a single chemical element. Building upon our foundational knowledge of mineralogy, crystals, crystal systems, the Mohs scale, and silicate minerals, we now focus on these unique substances. We'll examine the different groups of native element minerals, including metals, semimetals, and nonmetals, and discuss their properties, occurrences, and economic significance. Examples like gold, silver, copper, sulfur, and diamond will illustrate the diversity and importance of this mineral group. This understanding will lay the groundwork for future discussions on mineral cleavage, crystal habit, optical mineralogy, and X-ray crystallography.
