Question

Define

a) Crystal lattice

b) Unit cell​

Answer 1

Answer:

Crystal lattice is a regular arrangement of the constituent atoms or ions or molecules in three-dimensional space. A crystal lattice also called a space lattice or simply, a lattice. There are only 14 possible three-dimensional lattices. These are called Bravais’ lattices.

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

hope it help

Answer 2

Answer:

crystal lattice the arrangement of atoms, molecules, or ions of a crystal in the form of a space lattice.

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.
