Minerals are materials that after millions of years take their most stable form. Crystals are structures that are always preferred relatively to the amorphous state. That's why almost every mineral is crystalline. For example As2S3 melts always results in an amorphous-glassy solid (phase change material used in CDs) but in the nature it is a crystalline solid known as orpiment (a yellow dye).

Why is cole not considered a mineral?
Coal is not considered a mineral because it is an organic material formed from the remains of ancient plants and animals, rather than being a naturally occurring inorganic substance. Minerals are defined as naturally occurring, inorganic solids with a definite chemical composition and crystalline structure. Since coal is composed of carbon and other elements derived from organic matter, it does not meet these criteria. Additionally, coal lacks a uniform crystalline structure, further disqualifying it as a mineral.
Is a crystal structure an essential characteristic of any mineral?
Yes, a crystal structure is an essential characteristic of any mineral. Minerals are defined as naturally occurring inorganic solids with a specific chemical composition and a crystalline structure, which gives them unique physical properties. The arrangement of atoms in a crystal lattice influences the mineral's hardness, cleavage, and other characteristics. Without a defined crystal structure, a substance would not be classified as a mineral.
What is the definition of minerals?
Minerals are the components in the Earth that combine to form rocks. Minerals are inorganic naturally occurring substances, have a definite range of chemical composition, are solids, and have a crystalline structure.Minerals are solid, inorganic substances made from a combination of chemical elements.a solid, naturally occurring inorganic substance.
Is a lab created diamond a mineral?
A lab-created diamond is not classified as a mineral in the traditional sense, as minerals are naturally occurring inorganic solids with a defined chemical structure. While lab-created diamonds have the same chemical composition and physical properties as natural diamonds, their synthetic origin distinguishes them from natural minerals. Thus, while they share similarities with natural diamonds, they do not fit the strict definition of a mineral.
Why is acrylic and glass not a mineral?
Acrylic and glass are not considered minerals because they are synthetic materials rather than naturally occurring substances. Minerals are defined as naturally occurring, inorganic solids with a crystalline structure and a specific chemical composition, whereas acrylic is a polymer made from acrylic acid and glass is typically composed of silica and other additives, both of which are processed and manufactured. Additionally, neither acrylic nor glass possesses a crystalline structure, which is a key characteristic of true minerals.
How can you determine if a mineral is a mineral?
If you are starting with a mineral, there is no need to determine if it is a mineral. Minerals are naturally occurring inorganic solids, with a specific chemical formula and a crystalline structure. If the material in question does not meet this definition, it probably isn't a mineral.
What is the difference between a crystaline mineral and an amorphous mineral?
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
Why aren't solids minerals?
A mineral is determined as a lattice-structured repeating crystal. While all minerals are solids, there are solids which are not lattice-structured, not repeating, and not crystalline. As a result, those solids are not minerals.
Particles have an orderly arrangement in this type of solid.?
crystalline solids
Are all minerals crystalline?
A mineral, by definition is an inorganic solid with a crystalline structure formed naturally. Wood, paper, or any other organic solids are not minerals because they have no crystalline structure and form organically. Plastic is not a mineral either because it is made synthetically out of organic materials. Some organic materials like coal and other hydrocarbons are considered minerals economically. Bones and teeth contain hydoxylapatite that is organically formed but is still considered a mineral, so there are exceptions. Whewellite is organically formed but has a crystalline structure, and is considered a mineral.
Rubber and glass which become softer as they are heated are examples of?
Rubber and glass which become softer as they are heated are examples of crystalline solids
Is it true that rubber and glass are examples of crystalline solids?
No, rubber and glass are examples of amorphous solids, not crystalline solids. Crystalline solids have a repeating atomic arrangement, while amorphous solids lack a regular, ordered structure.
What is a crystalline solid-?
Crystalline solids are a class of solids that have regular or nearly regular crystalline structures. This means that the atoms in these solids are arranged in an orderly manner. Examples of crystalline solids are sugar, sugar candy, or rock candy.

What is a kind of mineral that occurs in crystalline form It is the most common of all solids minerals and may be colorless and transparent as well as colored?
Quartz
Are crystalline and amorphous solids?
Crystalline Solids are when the particles form a regular repeating pattern. Amorphous solids have particles that are not arranged in a regular pattern.
Does crystalline solids have plasticity?
No they do not.
