define unite cell and explain type of units cell
Answers
Answer:
A unit cell is the smallest repeating portion of a crystal lattice. ... 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-centered cubic . These are shown in three different ways in the Figure above
Answer:
Unit cell : the smallest group of atoms which has the overall symmetry of a crystal, and from which the entire lattice can be built up by repetition in three dimensions.
Types Of Unit Cell
There are two types of unit cells – Primitive and Centred Unit Cells.
Primitive Unit Cells:
When particles in unit cell are present only at the corners, it is called the primitive unit cell or the unit cell constructed so that it contains only one lattice point is called primitive cell means that there is n number of cells sharing the lattice point, each vertex of the cell sits on a lattice point which is shared with the surrounding cells and each lattice point is said to contribute 1/n to the total number of lattice points in the cell.
