The title is correct.
- intrasight 9y agoThen I am just not familiar with this use of the term "compound". I was thinking synonymous with "mineral", as in https://en.wikipedia.org/wiki/Mineral https://en.wikipedia.org/wiki/Mineral "Minerals are chemical compounds, and as such they can be described by fixed or a variable formula." But now I think it means like: http://www.scienceclarified.com/everyday/Real-Life-Earth-Science-Vol-2/Rocks-Key-terms.html http://www.scienceclarified.com/everyday/Real-Life-Earth-Sci... "COMPOUND: A substance made up of atoms of more than one element, chemically bonded to one another"
