MC. Crystal Structures

As noted in MM. Molecules, crystals are generally difficult to identify in terms of common molecules. Nevertheless individual crystals can be identified in terms of their most common molecules MC(). Crystals can also be classified in terms of structure. The elements studied to date as solid samples have eight kinds of crystal structures:

1. Cubic

2. Body-centered cubic

3. Face-centered cubic

4. Hexagonal

5. Monoclinic

6. Orthorhombic

7. Rhombohedral

8. Tetragonal.

For some of the synthetically produced transuranic elements, available samples have been too small to determine crystal structures. It would be possible to identify some crystals used linked notation with the classification of shapes [See N Main Class]
