Crystal

A clear or apparent solid is a solid actual whose basic atoms, molecules, or ions are abiding in an alike repeating arrangement extending in all three spatial dimensions. The accurate abstraction of crystals and clear accumulation is accepted as crystallography. The action of clear accumulation via mechanisms of clear advance is alleged condensate or solidification. The chat clear is acquired from the Ancient Greek chat κρύσταλλος (krustallos), acceptation both “ice” and “rock crystal”,[1] from κρύος (kruos), “icy cold, frost”.[2][3]

Most accepted metals are polycrystals. Crystals are generally symmetrically intergrown to anatomy clear twins.
