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.
Every mineral has a unique arrangement of elements within its inherent structure. This arrangement of atoms determines a mineral type. All minerals have a chemical formula, which is an analysis of the types and amounts of elements present in a mineral.
