A mineral is a pure substance that is solid and has a specific gravity greater than 1 g/cm3
|
|
|
A mineral is a crystalline substance in which atoms are arranged in a regularly repeating and orderly pattern (symmetry).

|
A mineral is a naturally occurring compound found deep in the Earth’s crust

None of the above

Detailed explanation-1: -A crystalline solid is a mineral. A crystal structure is an arrangement of atoms that comes together in a highly ordered, repeating symmetrical pattern. The arrangement forms a crystal lattice. This lattice forms a crystal.
Detailed explanation-2: -By definition (with just a few special exceptions) minerals must be crystalline. This means that they are solids with an orderly repetitive atomic arrangement.
Detailed explanation-3: -Minerals Definition Mineral is a naturally occurring inorganic solid with a definite chemical composition and a crystalline structure. The earth is composed of mineral elements, either alone or in a myriad of combinations called compounds. A mineral is composed of a single element or compound.
Detailed explanation-4: -Minerals also have a definite chemical composition in which the atoms are arranged in an orderly pattern called the “crystalline structure".
Detailed explanation-5: -All minerals have a(n) crystal structure, which means the atoms are arranged in an orderly, repeating pattern; this causes minerals to often have sharp edges and smooth faces. A mineral is always made of specific amounts of specific elements; therefore, minerals always have a(n) chemical formula.
