How crystal forms are denoted
WebCrystals are all around you in many different forms, such as gemstones, salt, and even in your computer screen. There are many ways that crystals are formed, such as the … WebThe symbols used in crystallography mean the following: Cn (for cyclic) indicates that the group has an n -fold rotation axis. Cnh is Cn with the addition of a mirror (reflection) plane perpendicular to the axis of rotation. Cnv is Cn with the addition of n mirror planes parallel to the axis of rotation.
