Answer 1

Explanation:

hii mate heres ur answer

the group of atom is called the basis .when repeated in space it form crystal structures .the basis consist of primitive cell containing one single lattice point arranging one cell in each lattice point will fill up entire crystal

hope it help

Thank you
