Which of the following unit cells has the highest symmetry?
- hexagonal
- orthorhombic
- cubic
- monoclinic
Explanation
The unit cell with the highest symmetry is cubic.
Among all crystal systems, the cubic unit cell has the highest symmetry because:
-
All sides are equal:
-
All angles are right
-
It has multiple axes of symmetry and mirror planes
This high degree of symmetry leads to highly uniform and isotropic properties.
