Packing in solids

Science > Chemistry > Solid State > Packing in solids In this article, we shall study the different types of close packing of the constituent particles in solids. The Principle of Packing in Solids: In a crystal particle (atoms, molecules or ions) occupy the lattice points in the crystal lattice. These particles may be of […]

9 Comments on Packing Efficiency of Unit Cell

Science > Chemistry > Solid State > Packing Efficiency of Unit Cell In this article, we shall study the packing efficiency of different types of unit cells. In whatever way the constituent particles atoms, molecules or ions are packed, there is always some free space in the form of voids. The fraction of the total […]

Bravais Lattices

Science > Chemistry > Solid State > Bravais Lattices In this article, we shall study the structures of Bravais Lattices. A crystal is a homogenous portion of a solid substance made of a regular pattern of structural units bonded by plane surfaces making a definite angle with each other. Unit Cell: A unit cell is […]

No Comments on Classification of Crystalline Solids

Science > Chemistry > Solid State > Classification of Crystalline Solids In this article, we have to study classification of crystalline solids and characteristics of each type. Broadly crystalline solids are classified into 4 types. a) molecular solids, b) ionic solids, c) metallic solids, and d) covalent solids Molecular Solids: Molecular solids are crystalline solids […]

1 Comment on Introduction to Solid State

Science > Chemistry > Solid State > Introduction to Solid State There are three states of matter, solid, liquid and gaseous. Liquids and gases are called fluids because of their ability to flow. The fluidity in both of these states is due to the fact that the molecules are free to move about. The free mobility […]
