A possible crystal structure of Gold is face-centered cubic structure. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. The forces of chemical bonding causes this repetition.
In mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals. The habit of a crystal is dependent on its crystallographic form and growth conditions, which generally creates irregularities due to limited space in the crystallizing medium (commonly in rocks). WebA crystal habit describes the overall trend of growth of crystals in a crystal cluster: in a cubic crystal habit, crystals tend to form mainly in cube shapes. However, in a botryoidal crystal habit, crystals tend to form in globular, spherical patterns similar in appearance to a cluster of grapes.
