Chapter 12, Problem 29E

Interpretation Introduction

Interpretation:

The name of element which crystallizes in body centered cubic structure is to be stated.

Concept introduction: Unit cell is the smallest repeating unit of the crystal lattice. Basically crystal lattice is an arrangement of unit cell in geometrical manner. Unit cells are also known as building blocks of crystal lattice. The unit cells are divided in two categories named as, primitive and centered unit cells. The centered unit cells are further divide as,

• Body-centered unit cell (BCC).
• Face-centered unit cell (FCC).
• End-centered unit cell (ECC).

The total number of atoms present is body centre unit cell is equal to two. While in case of face centered it is four. Density of the body centered cubic unit cell is always lower than the face centered unit cell.

To determine: The name of element which crystallizes in body centered cubic structure.
