Question
1. Radii were reported as follows: Tit+ = 60 pm; 0²- = 140 pm. Based on this, tell as much as you can about the expected structure of TiO₂ - provide the hole type for the cation, the cell lattice, and the coordination numbers for both cation and anion.

Expert Solution
Step 1

TiO2 is a tetragonal structure lattice.

Ti4+ = 60 pm 

O2- = 140 pm 

So, r+/r- = 60/140 = 0.428

So, Octahedral void is present.
