Question

Suppose the atoms in a two-dimensional crystal have the following arrangement:  On the drawing below the lines connect four spheres which represents the unit cell of this crystal.

Quizplus · Accepted Answer

The given arrangement shows a repeating unit of four atoms, which represents a unit cell of a crystal lattice. The connecting lines between the spheres illustrate this unit cell in a two-dimensional crystal structure. Therefore, the statement is true.
