No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
Fluoride is an ion. Flourite is a mineral. Like all minerals, it is crystalline.
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.
The presence of hot fluids causes the mineral crystals to become extremely large.
All minerals have a crystal form, but not all have cleavage.

Yes, the crystal system a mineral belongs to is a property of a mineral.

A mineral crystal is not necessarily a diamond, but a diamond is a mineral crystal. All minerals, such as diamond, have crystalline structures.
A crystal mineral is a solid composed of material extending in all spatial dimensions.
Yeah, you can melt anything if you get it hot enough. Be sure not to confuse the terms crystal and mineral. A crystal is made of a mineral, the fact that it is a crystal, simply means that it's atoms are arranged in a periodical and static way, in the crystal structure. This structure falls apart as soon as the mineral melts, so a molten mineral can not be called a crystal.
No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Diamond is one mineral in the isometric crystal system.
A mineral's crystal shape is determined by its internal structure, specifically the arrangement of its atoms or molecules. As the mineral grows, the atoms or molecules arrange themselves in a repeating pattern according to the mineral's unique crystal lattice structure, leading to the formation of distinct crystal shapes such as cubes, hexagons, or prisms. Factors like temperature, pressure, and surrounding environment can also influence a mineral's crystal shape.

Mineral crystal formation is a naturally occurring process of inorganic material. Crystal formation can occur in organic material as well, but would not be considered mineralogical crystal formation.
