In this lesson, we will learn how to determine stoichiometries of atoms and ions in cubic lattices based on Bravais lattice type and hole occupancies.
Q1:
The radius of a cation in a cubic ionic lattice is 70% smaller than the radius of the anion. The charges of the cation and anion are equal in magnitude. What type of hole is the cation likely to occupy?
Q2:
NaCl and ZnS both have face-centered cubic structures. Why do the sodium ions in NaCl have a higher coordination number than the zinc ions in ZnS?
Q3:
What type of hole do lithium ions occupy in the cubic lattice of LiSe2?
