Since the crystals do possess a three dimensional arrangement of atoms, there are some regularities related to their faces and hence angles among them. Many crystals do show twinning which does happen during the growth of crystals.
Crystal Symmetry Crystal Symmetry By Tirumala Prasad Symmetry in crystals is due to the orderly arrangement of atoms. Such an arrangement of atoms is known as the lattice. In crystals there is a three dimensional arrangement of atoms. Such an arrangement is known as the space lattice. The imaginary lines drawn through the crystal lattice are known as the crystallographic…Read More
