internal arrangement of atoms
Pyrite is a mineral that exhibits a cubic crystal structure. It has a distinct metallic luster and a brassy yellow color, often forming cubic or pyritohedral crystals.
The crystal shape of halite is typically cubic due to its atomic structure and arrangement of sodium and chlorine ions. The perfect cubic cleavage of halite is a result of its strong ionic bonds between the sodium and chlorine ions, which break easily along planes of weakness, resulting in flat, smooth surfaces when the mineral is fractured.
Mineral crystals can appear in any of the six crystal systems (cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal) depending on their internal atomic arrangement. The structure and symmetry of a mineral crystal is determined by factors such as its chemical composition and how the atoms are arranged within the crystal lattice.
The shape of the crystals in a mineral sample demonstrates the mineral's internal atomic arrangement and growth conditions. Different crystal shapes, such as cubic, hexagonal, or prismatic, indicate how the mineral's atoms are organized and bonded. This crystallographic property is called the mineral's crystal habit.
A hypothesis for mineral identification could be that specific physical and chemical properties, such as hardness, color, luster, and crystal structure, can be used to accurately classify minerals into distinct categories. For example, "If a mineral exhibits a Mohs hardness of 7, a vitreous luster, and a cubic crystal habit, then it is likely to be identified as quartz." This hypothesis can be tested by examining various minerals and comparing their properties to known standards.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
internal atomic arrangement, specifically the arrangement of atoms in a repeating pattern that gives rise to the crystal's shape. The cubic shape reflects the natural tendency of atoms to arrange themselves in a symmetrical and orderly manner.
The shape of a mineral depends on the chemical structure that the bonds form between atoms in the mineral. A cubic mineral (such as pyrite) has a chemical structure that, as bonds are made, a cubic shape is formed.
Diamond is one mineral in the isometric crystal system.
Pyrite is a mineral that exhibits a cubic crystal structure. It has a distinct metallic luster and a brassy yellow color, often forming cubic or pyritohedral crystals.
This crystal is face-centered cubic.

Halite is table salt. The cubic crystal "galena" is lead sulfide.
Cubic zirconia is not considered a mineral because it is a synthetic material created in a laboratory. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. Cubic zirconia is a man-made replica of the mineral zirconium dioxide, often used as a diamond simulant due to its brilliance and clarity.
Halite has a cubic crystal structure, which makes it naturally form into perfect cubes. When broken repeatedly along its natural cleavage planes, halite will continue to fragment into smaller cubes due to its internal molecular arrangement. This phenomenon is a result of the crystal structure of halite and its tendency to break along specific planes.
