In this problem, we are asked to identify the shown structure of Lithium oxide and Silver iodide as the structure of rock salt, zinc blende, fluorite, antifluorite, or none of the given choices.
Recall that unit cells are the smallest divisible unit of a crystal that, when repeated in three dimensions, reproduces the entire crystal lattice.
We are given the figure of the structure of the unit cell of the compound:
We can see that that structure is cubic, with 1 atom in each corner of the cube.
We can also see that there is 1 atom in every cube face. Thus, the two unit cells shown is a face-centered cubic unit cell.
