Indium has a tetragonal unit cell, a distinctive crystal structure that sets it apart from other metals. This unique arrangement of atoms gives indium a remarkable set of properties, making it a valuable material in various industries and technologies.
The tetragonal unit cell of indium consists of a rectangular prism with square bases. The atoms are arranged in a face-centered cubic lattice, with each atom surrounded by eight nearest neighbors. This arrangement results in a high degree of symmetry and a strong metallic bond.
Indium’s Crystal Structure
Indium crystallizes in a tetragonal unit cell, which is a three-dimensional arrangement of atoms that repeats itself throughout the crystal. The unit cell of indium has a square base with four atoms at the corners and two atoms in the center.
The height of the unit cell is equal to the length of the base.
Arrangement of Atoms within a Tetragonal Unit Cell
The atoms in a tetragonal unit cell are arranged in a repeating pattern of layers. Each layer consists of four atoms arranged in a square. The layers are stacked on top of each other in a regular fashion, with the atoms in each layer directly above or below the atoms in the layer below.
