Q.
The total number of elements of symmetry in a cubic crystal is
The Solid State
Solution:
Total number of elements of symmetry $=23$
Rectanglular plane of symmetry $=3+$ Diagonal plane of symmetry $=6+$ centre of symmetry $=1+$ axis of symmetry $=13$
$[3$ fold $=4,2$ - fold $=6,4$ fold $=3] \rightarrow$ axis of symmetry.
