Nothing that was once part of a living thing
no because a mineral must be inorganic. a shell is organic.
A mineral must be, in addition to being inorganic, be a solid, naturally occurring, in crystalline form, and have a set chemical formula.
a mineral is defined as any inorganic substance that occurs in nature and has a definite chemical composition.
In order to be a mineral, something must be solid, inorganic, naturally-occurring, chemically-defined, AND crystalline. If it is not one of these things, it is not a mineral!
a mineral is defined as any inorganic substance that occurs in nature and has a definite chemical composition.
5 characteristics of a mineral are: 1. Has to be a solid 2. Has to be inorganic 3. Has to occur in nature 4. Has to have a definite chemical composition 5. Has to have a crystalline structure
The solid material must have a crystalline structure, be inorganic, have definite chemistry parameters, and be naturally occuring.
A mineral must be a naturally occurring, homogeneous solid with a defined chemical composition and a highly ordered atomic arrangement.
To be naturally-occurring, the substance must not be man made. The inorganic requirement states that the substance must not be constructed by an organism. The solid characteristic eliminates any substance that is liquid or gas. Definite chemical composition means that the substance must have chemical composition that falls within a specific range. The characteristic that requires the substance to have an ordered internal structure states that the atoms are arranged in a repeating pattern.
A mineral must be a solid, have a definite chemical formula, have a crystalline structure, and be naturally occuring.
If it also has a crystalline structure, it would be called a mineral.
Minerals, although they can "grow" as crystals, are not alive and are therefore classified as inorganic matter.To be classified as a mineral, a substance must be a solid, have a crystalline structure, be inorganic, be naturally occuring, and have a very specific range of chemical formulae.
