Crystallographic cell

What are the 3 types of unit cells?
A unit cell can either be primitive cubic, body-centred cubic (BCC) or face-centred cubic (FCC).
In this section, we will discuss the three types of unit cell in detail..
What is a crystalline unit cell?
A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal.
A crystal can be thought of as the same unit cell repeated over and over in three dimensions..
What is the crystallographic element?
These are the cubic, tetragonal, orthorhombic, monoclinic, triclinic, trigonal and hexagonal.
Some of these are further subdivided to give 14 in all..
The unit cell can be seen as a three-dimensional structure containing one or more atoms.
We can determine the volume of this unit cell with the knowledge of the dimensions of the unit cell.
For example: if we have a unit cell of an edge “a”, the volume of the unit cell can be given as “a³”.

Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells

The defining property of a crystal is its inherent symmetry

By considering the arrangement of atoms relative to each other, their coordination numbers, interatomic distances, types of bonding, etc.

Real crystals feature defects or irregularities in the ideal arrangements described above and it is these defects that critically determine many of

The difficulty of predicting stable crystal structures based on the knowledge of only the chemical composition has long been a stumbling block on the
