diamond crystal system

Diamond is the purest form of natural carbon. It occurs as small crystals embedded in rocks. These are supposed to have been formed by the crystallization of carbon under extreme pressure and temperature in the interior of the earth. Nowadays, synthetic industria..

The Seven Crystal System - Crystals along with suitable examples are listed in the table. System Axial distances Axial angles Examples Cubic a = b = c α = β = γ = 90° NaCl,KCl, Diamond, Cu, Ag Tetragonal a = b ≠ c α = &..

Calculation of Number of Particles per Unit Cell of a Cubic Crystal System - Calculation of Number of Particles per Unit Cell of a Cubic Crystal System. Keeping the following points in mind we can calculate the number of atoms in a unit cell. An atom at the c..

In covalent crystals, the constituent particles are atoms of the same or different kind, which are bonded to one another by a network of covalent bonds. The important characteristics of covalent crystals are: The covalent crystals are incompressible and hard. The..

Calculation of Number of Particles per Unit Cell of a Cubic Crystal System. Keeping the following points in mind we can calculate the number of atoms in a unit cell. An atom at the corner is shared by eight unit cells. Hence an atom at the corner contributes 1/8 to the uni..

Any system where there is a constant exchange of matter and energy from the surrounding environment is called as open system. All living organisms represent open systems. Any state of a system where the rate of input of energy and matter is equal to the ra..

Graphite is found widely distributed in nature, viz., in Siberia, Sri Lanka, USA, Canada. Large quantities of graphite are also manufactured from coke or anthracite in electric furnaces. Diamonds and graphite are two crystalline allotropes of carbon. Diamond and graphite both a..

The existence of an element in more than one form, in the same physical state, is called allotropy. The various forms are called allotropes. Allotropy is the result of different arrangement of the atoms in the crystal structure of the element. As a result, the allotropes exhibit very diff..

In covalent solids, the constituent particles are atoms of same or different kinds. Covalent bonds network, forming a continuous giant interlocking structure of atoms throughout the crystal that hold them together. They are also referred to as covalent network solids. Because, covalent bo..
