Chapter 15, Problem 15.3P

Interpretation Introduction

Interpretation:

Orthorhombic unit cell has to be drawn and marked on it the given plans.

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.
• Face centred cubic unit cell: The identical particles present in the eight corners of the u it cell.  But this structure contains same particle in the six centres of the faces.
• Body centred cubic: Body cantered cubic cell is the type of crystal structure in metal.  This cubic structure cab be seen as a congregation of cubes with atoms at the edges and in the canter of all cube.
