Question

define unit cell and it's type​

Answer 1

Answer:

A unit cell is the smallest repeating portion of a crystal lattice. Unit cells occur in many different varieties. As one example, the cubic crystal system is composed of three different types of unit cells : (1) simple cubic , (2) face- centered cubic , and (3) body

Answer 2

The unit cells which are all identical are defined in such a way that they fill space without overlapping. The 3D arrangement of atoms, molecules or ions inside a crystal is called a crystal lattice. It is made up of numerous unit cells. One of the three constituent particles takes up every lattice point.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.
