Chapter 11, Problem 11.83QP

Interpretation Introduction

Interpretation:

Atoms in simple cubic unit cell of an atomic crystal in which each atom is at lattice points have to be identified.

Concept introduction:

• Crystal structure: Crystal structure is arrangement of group of atoms or ions or molecule in the crystalline material.
• Unit cell: A simplest repeating unit in the crystal structure. Every unit cell is described in terms of lattice point.  Example for unit cell: cubic, monoclinic, tetragonal, orthorhombic, rhombohedral, hexagonal and triclinic.
• Simple cubic unit cell: The unit cell in which lattice points are located at the corners.
