Question

Difference between primitive and non primitive unit cell

Answer 1

The primitive unit cell contain only one lattice point which is made up from the lattice point at each of the conners lattice point on the face on rhe unit cell are shared between two unit cell and are worth 1/2of lattice point per unit cell

Answer 2

QUESTION:-

Difference between primitive and non-primitive unit cell

ANSWER:-

In geometry, The Unit Cell is known as a parallelepiped, which provides six lattice parameters that are taken as the edges lengths of the cells and the angles between them. Unit cell are of two types: Primitive unit cell and Non-primitive unit cell.

Difference Between Primitive And Non Primitive Unit Cell

• In the Primitive Unit Cell, is a unit cell which contains one lattice point. Whereas, a Non-primitive Unit Cell is a unit cell which consists of particles that are present not only at the corner but also in the centres of the face and body of the unit cell.

• In a Primitive Unit Cell, the particles that are constituents are only present at the corners of a unit cell. Whereas, In the Non-primitive Unit Cell, the particles that are constituents are present at the corner and the centres of the face and body of the unit cell.

• In Primitive Unit Cell, all basic unit cells are linked with a single lattice point and are also called P-cells. Whereas, In the Non-primitive Unit Cell the unit cells are linked with more than one lattice point and are also called multi-unit cells.

• In the Primitive Unit Cell, the changes that are made to the copy are not evaluated in the original. Whereas, in the Non-primitive Unit Cell, the changes that are made to the copy as evidence of the original.
