WebAug 23, 2024 · The crystalline shape is a hexagonal prism. And at each corner of this hexagonal prism have one atom. And also, at the center of the top and bottom surfaces of the hexagon prisms, there is one atom. So, at each hexagon surface, there are 7 atoms. And also, there is a triangular 3 atoms in the middle between these two surfaces. WebFigure 12.6.6: The General Features of the Seven Basic Unit Cells. The lengths of the edges of the unit cells are indicated by a, b, and c, and the angles are defined as follows: α, the angle between b and c; β, the angle between a and c; and γ, the angle between a and b. Cubic: a = b=c, alpha= beta=gamma = 90 degrees.
