Minerals

Naturally occurring substance that is solid and stable at room temperature, representable by a chemical formula, usually abiogenic, and has an ordered atomic structure. It is different from a rock, which can be an aggregate of minerals or non-minerals, and does not have a specific chemical composition. The general definition of a mineral encompasses the following criteria: 1 - Naturally occurring 2 - Stable at room temperature 3 - Represented by a chemical formula 4 - Usually abiogenic 5 - Ordered atomic arrangement
