Chapter 21, Problem 21.37E

Interpretation Introduction

Interpretation:

Whether the assumption of Crystallography that the crystal has a simple cubic unit cell by calculating the values of $\left(h^2+k^2+l^2\right)$ is valid or not is to be predicted. The verification for the same is to be stated.

Concept introduction:

A unit cell of the crystal is the three-dimensional arrangement of the atoms present in the crystal. The unit cell is the smallest and simplest unit of the crystal which on repetition forms an entire crystal. Unit cell can be a cubic unit cell or hexagonal unit cell. The classification of a unit cell depends on the lattice site occupied by the atoms.
