Question

Quizplus · Accepted Answer

The statement that a crystallographic unit cell has corners with 90° angles is not always true. Unit cells can have angles that are not 90°, as seen in monoclinic, triclinic, and hexagonal crystal systems. The other statements accurately describe characteristics of a crystallographic unit cell.
