Applications of lonic Packing and Properties: 1. Spinels (Balas Rubies) The spinel crystal lattice has an empirical formula of A²*B23*O4². The original spinel mineral was identified as containing Al, O, and Mg. Write the empirical formula for this original spinel. Part of the spinel unit cell involves the tetrahedral coordination of a magnesium ion by four oxygen ions. In the empty lattice given below, draw in the Mg and O ions. Magnetic atoms/molecules result from the presence of unpaired electrons. In some minerals with a spinel crystal structure, the Mg ions are replaced by Fe ions of the same charge. Show the electron configurations for the magnesium ion and the iron ion. Explain why the structure containing the Mg cations is non-magnetic while the structure containing the Fe cations is magnetic.
