11.4.2: Unit Cell Symmetry and Crystal Symmetry

The cube, octahedron, and dodecahedron are all special forms that have the same symmetry as the unit cell, 4/m32/m. Tetrahedrite crystals (Figures 11.36 d and 11.40), in contrast with the other three, do not have the same symmetry as their unit cell. Although made of cubic unit cells, the crystals lack 4-fold rotation axes.

Where does salt come from? - UC Santa Barbara

Because salt is so soft, it moves really easily and can pierce through other rock units. Regions in Iran actually contain salt glaciers which can flow over the landscape. This occurs because the region is too arid for rain to dissolve the salt. Answer 4: Chemically, salt is the combination of a sodium ion and a chlorine ion.
