9 some scientists actually consider the exosphere as part of outer space as there is such a gradual and fuzzy distinction between the density of molecules in the very upper reaches of the atmosphere and lower reaches of space
Notice that graphite, commonly seen in pencil lead, and diamonds. have the same chemical formula. Minerals with the same chemical formula but. different crystal structures are called polymorphs. These minerals have different. types of chemical bonds and, thus, different crystal forms. If a substance fails any part of this definition, it is not a mineral. For example, table sugar, an organic compound formed by biological plant activity, fits all. facets of the definition except the inorganic part.
Minerals are inorganic compounds -- ones not based on carbon and hydrogen -- and are smaller particles that come mostly from natural geological processes. They have a simple chemical structure compared to vitamins, which can have large and complex chemical structures.
