WebYou could describe this crystal structure as ... When you’re talking about the crystal structure of real, 3D crystals you need to include the lattice and the basis. For example the Cu crystal structure is a cube with side length 0.3615 nm and 8 Cu atoms. There are 4 Cu atoms at positions (0,0,0), (½, ½, 0), (½, 0, ½,) and (0, ½, ½). The defining property of a crystal is its inherent symmetry. Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis. In addition to … WebA formal definition of a mineral, as used by geologists would be: A naturally occurring inorganic solid that has a definite chemical composition, and an ordered internal structure.
