Describe the crystal structure of mineral
WebMinerals can be identified by the shape of their crystals or crystallography. The shapes of crystals are determined by a number of factors such as the size and length of their … In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating p…
