Answer 1

Hey mate here is your answer :

Lattices can be classified into "systems", each system being characterized by the shape of its associated unit cell. In three dimensions, the lattices are categorized into seven crystal lattice "systems". Within several of these, lattices supporting non-primitive unit cells can be defined.

Answer 2

Answer:

Explanation:

The group of atoms is called the basis; when repeated in space it forms the crystal structure. The basis consists of a primitive cell, containing one single lattice point. Arranging one cell at each lattice point will fill up the entire crystal.
