Question
What mineral crystal structure is this?
- Hexagonal
- Tetragonal
- Cubic
- Triclinic
Hint:
Triclinic has the least symmetry.
The correct answer is: Triclinic
- The hexagonal unit cell is a hexagonal prism with atoms on all 12 corners.
- The tetragonal unit cell is a distortion of the simple cubic unit cell.
- The cubic unit cell is the simplest unit cell with atoms at 8 corners.
- The triclinic unit cell has the least symmetry, length, breadth, and height all are different.
