A crystal is a material made up of a three- dimensional periodic ordering of atoms, ions,or molecules. Single Crystal:Three-dimensional ordering repeated indefinitely throughout its volume.In single crystals,the periodicity,or ordering,of atoms,ions,or molecules determines the variability in bonding along different directions within the crystal
