Spinel is a important class of oxides consisting of two types of metal ions with the oxide ions arranged in CCP pattern. The normal spinel has one-eight of the tetrahedral holes occupied by one type of metal ion and one half of the octahedral hole occupied by another type of metal ion. Such a spinel is formed by Zn2+, Al3+ and O2-, with Zn2+ in the tetrahedral holes. Give the formulae of spinel.

Zn2+ = 8/8 = 1
Al3+ = 4/2 = 2
O2– = CCP (4)
ZnAl2O4
Al3+ = 4/2 = 2
O2– = CCP (4)
ZnAl2O4
O2– = CCP arrangment (1+3) = 4

Spinel Structure
- Spinel is a type of oxide structure consisting of two types of metal ions (M1 and M2) with the oxide ions arranged in a ccp pattern.
- The normal spinel has one-eighth of the tetrahedral holes occupied by M1 and one-half of the octahedral holes occupied by M2.
Formulae of Spinel
- The spinel formed by Zn2+, Al3+ and O2- has the formula ZnAl2O4.
Edge Length, Density and Number of Atoms per Unit Cell
- The edge length of the unit cell can be calculated using the formula a = 4r/√2, where r is the radius of the oxide ion.
- For the spinel structure, the edge length is a = 8r/√3.
- The density of the unit cell can be calculated using the formula Density = (Z x M) / (V x Na), where Z is the number of atoms in the unit cell, M is the molar mass of the unit cell, V is the volume of the unit cell and Na is Avogadro's number.
- For ZnAl2O4, the number of atoms in the unit cell is 8 (4 oxygen atoms, 2 aluminium atoms and 2 zinc atoms), the molar mass is 193.3 g/mol, and the volume of the unit cell can be calculated using the formula V = a^3, where a is the edge length.
- Using these values, the density of the unit cell is calculated to be 4.42 g/cm^3.
Therefore, the correct answer is option A, ZnAl2O4.
- Spinel is a type of oxide structure consisting of two types of metal ions (M1 and M2) with the oxide ions arranged in a ccp pattern.
- The normal spinel has one-eighth of the tetrahedral holes occupied by M1 and one-half of the octahedral holes occupied by M2.
Formulae of Spinel
- The spinel formed by Zn2+, Al3+ and O2- has the formula ZnAl2O4.
Edge Length, Density and Number of Atoms per Unit Cell
- The edge length of the unit cell can be calculated using the formula a = 4r/√2, where r is the radius of the oxide ion.
- For the spinel structure, the edge length is a = 8r/√3.
- The density of the unit cell can be calculated using the formula Density = (Z x M) / (V x Na), where Z is the number of atoms in the unit cell, M is the molar mass of the unit cell, V is the volume of the unit cell and Na is Avogadro's number.
- For ZnAl2O4, the number of atoms in the unit cell is 8 (4 oxygen atoms, 2 aluminium atoms and 2 zinc atoms), the molar mass is 193.3 g/mol, and the volume of the unit cell can be calculated using the formula V = a^3, where a is the edge length.
- Using these values, the density of the unit cell is calculated to be 4.42 g/cm^3.
Therefore, the correct answer is option A, ZnAl2O4.
