If silver iodide crystallizes in a zinc blende structure withI^(-)ions forming the lattice, then calculate fraction of the tetrahedral voids occupied byAg^(+) ions.

If silver iodide crystallizes in a zinc blende structure withI^(-)ions

1.	If silver iodide crystallizes in a zinc blende structure withI^(-)ions forming the lattice, then calculate fraction of the tetrahedral voids occupied byAg^(+) ions.
Answer» SOLUTION : In AGL, If there are n`I^(-)`ions, there will ben ` Ag^(+)`ions. As ` I^(-)`ions form the lattice , number of tetrahedral voids = 2N, As there are n ` Ag^(+)`ions to occupy these voids, therefore, fraction of tetrahedralvoids occupied by `Ag^(+) " ions"= n //2n `= 1/2 = 50 % .
