In a cubic packed structure of mixed oxides, the lattice is made up of oxide, one fifth of tetrahedral voids are occupied by divalent ions (A2+), while one half of the octahedral voids are occupied by trivalent ions (B3+), then the formula of the oxide is:

A4B5O10

Answer is:

Answer is:

Explanation:

M = (d x a³ x N₀) ⁄ Z

Answer is:

The radius r⁺⁄r⁻ increases as coordination number increases

As the difference in the size of ions increases, coordination number increases

When coordination number is 8, the r⁺⁄r⁻ ratio lies between 0.225 and 0.414

In ionic solid of the type AX(ZnS, Wurtzite), the coordination number of Zn²⁺ and S²⁻ respectively are 4 and 4
