How do you describe a crystalline structure

WebCrystal formation requires two steps: nucleation and growth. Nucleation is the initiation step for crystallization. At the nucleation phase, protein molecules in solution come together as aggregates to form a stable solid … WebThese shapes are named after their geometry - for example, crystals based on cubes belong to the 'cubic or isometric' crystal group. There are seven main crystal groups or systems, as shown here. These are ordered from most symmetrical to lease symmetrical. Crystal group 1: Cubic (Isometric)
