We need to identify the type of structure of MnO by determining how many atoms are present on the MnO unit cell.
Edge length (a) = 4.47x10-8 cm
Density = 5.28 g/cm3
Let’s first calculate the volume of the unit cell:
MnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47 x 10-8 cm and the density of MnO is 5.28 g/cm 3. Assuming that the ionic radius of oxygen is 140. pm, estimate the ionic radius of manganese.
