WebFig 1: Types of Unit Cell. Primitive Cubic Unit Cell. In Primitive Cubic Unit Cell, the atoms are located only at the corners. This means that 8 atoms are placed on the lattice at 8 corners. Located at the corner, each atom contributes about 1/8 of the original cell’s volume. WebQ.9 An element crystallizes into a structure which may be described by a cubic type of unit cell having one atom on each corner of the cube and two atoms on one of its body diagonals. If the volume of this unit cell is 24×10–24 cm3 and density of element is 7.2 g cm–3, calculate the number of atoms present in 200 g of element.
