I think it's body centered cubic but I'm not completely sure.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
hexagonal crystal system ( 6 sided )
Corundum is in the trigonal crystal system.
it has a very tight crystalline structure and small but definite porosity
Yes, the mineral malachite does have a crystal structure.
Yes, the crystal system a mineral belongs to is a property of a mineral.
Yes, quartz belongs to the hexagonal crystal system, meaning that its crystal structure has six-fold symmetry.
The crystal system a mineral belongs to relates most to the mineral's internal atomic structure and arrangement of atoms. This determines the shape and physical properties of the mineral, such as its cleavage, hardness, and color.
The sulfate MgSO4.7H2O has a monoclinic structure.
Gold is not a crystal. It's amorphous. Solid gold given enough time will actually flow because it's very soft metal. Amorphous: MINERALOGY•CHEMISTRY (of a solid) not crystalline, or not apparently crystalline.
Halite crystals belong to the isometric crystal system. This means that the crystal structure exhibits cubic symmetry, with all edges of the crystal being of equal length and intersecting at 90-degree angles.
Diamond belongs to the crystal group of minerals known as the cubic system. This means that diamond crystals have a cubic structure, with symmetrical axes of equal length.
