If an ionic compound with the formula MX forms a primitive cubic unit cell with the anions (Xn^-)at the lattice points,the cations (M²ⁿ⁺)will occupy: A) all of the tetrahedral holes in each unit cell. B) half of the tetrahedral holes in each unit cell. C) the cubic hole in the center of each unit cell. D) the center of each face in each unit cell. E) all of the octahedral holes in each unit cell.

In a primitive cubic unit cell, the anions are at the corners, and the cation will occupy the cubic hole at the center of the unit cell to maintain charge neutrality and stoichiometry.
