Halite salt: The mineral Halite information and pictures
Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an …

10.5: Point Groups and Crystal Systems
Minerals belong to all seven crystal systems. About 10% of the common minerals are cubic, 10% are tetragonal, 10% are triclinic, 20% are hexagonal or rhombohedral; the remainder are 25% orthorhombic and 25% monoclinic. Within each system, different point groups have different amounts of symmetry. Most natural crystals fall into the point group ...

Crystal Definition, Examples, and Common Types
Cubic or Isometric: This shape includes octahedrons and dodecahedrons as well as cubes. Tetragonal: These crystals form prisms and double pyramids. The structure is like a cubic crystal, except one axis is longer than the other. Orthorhombic: These are rhombic prisms and dipyramids that resemble tetragons but without square cross …

Salt is composed of two elements; Sodium (Na) and Chlorine (Cl). Sodium and chlorine are strongly attracted to each other and stack together into a cubic crystal structure (see figure). Individual salt (halite) crystals have a cubic shape to them, which is mimicking the way that the individual elements are stacking together.
