• A crystal structure is a unique arrangement of atoms in a crystal.

• A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.

Answer 2

Answer:

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material. ... The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure.

Explanation:

In total there are seven crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. A crystal family is determined by lattices and point groups.
