Question

Explain Atomic packing factor and Unit cell.​

Answer 1

Explanation:

Atomic Packing Factor: ... It is defined as the volume occupied by combining total atoms of a unit cell in comparison to the total volume of a unit cell

Answer 2

In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. This is known as atomic packing factor(APF)

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. This is known as unit cell.
