Problem

The ionic substance strontium oxide, SrO, forms from the direct reaction of strontium metal with molecular oxygen. The arrangement of the ions in solid SrO is analogous to that in solid NaCl and is shown here. A diagram shows a three by three cube with alternating strontium and oxygen atoms.

In the figure, do the large spheres represent Sr2+ ions or O2- ions?
