Chapter 12, Problem 12.3VP

Interpretation Introduction

Interpretation: The chemical formula of the compound $\text{AB}$ from a unit cell is to be predicted.

Concept introduction: The unit cell is defined as the smallest part of a crystal lattice and the repetition of this smallest part in the three dimensional structure of crystal will make a complete crystal lattice.

The chemical formula from a unit cell is determined by counting total number of atoms present at the corners and inside the unit cell.

To determine: The chemical formula of the compound $\text{AB}$ from a unit cell.
