The total number of Bravais lattice arrangements in different crystal systems is

Distinguish between
$(i)$ Hexagonal and monoclinic unit cells
$(ii)$ Face-centred and end-centred unit cells.

If the edge length of a cubic unit cell of $Li$ having $bcc$ structure is $351 \, pm$, then the radius of the $Li$ atom will be ............ $pm$.

Tetragonal crystal system has the following unit cell dimensions:

The triclinic unit cell has the following parameters:

The body-centered unit cell is found in which of the following crystal systems?
