what are minerals ? on what basis can the minerals be identified ? give example
Answers
Answer:
ok so, here is your answer
Minerals are classified on the basis of their chemical composition, which is expressed in their physical properties. This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.
a mineral is a naturally occurring inorganic substance with a definite chemical composition and ordered atomic structure.
identified on the basis of their properties. eg. iron , gold , aluminum etc.
Examples of Minerals
Examples of MineralsTable salt is a mineral called sodium chloride. Its ordered structure is apparent because it occurs in crystals shaped like small cubes.

Coal is a mineral composed entirely of carbon, originally trapped by living organisms through the process of photosynthesis.

Coal is a mineral composed entirely of carbon, originally trapped by living organisms through the process of photosynthesis.The carbon in coal is therefore of organic origin which leads some authorities to object to the definition of a mineral as an inorganic substance.
