Why is SiO2 from the midterm polar instead of nonpolar?

My reasoning for putting SiO2 as polar was because of the slight difference in electronegativity. Since there was a slight difference in electronegativity, the compound did have ionic properties, but was not completely ionic.

I agree with Emily! On the midterm, I thought about it as Silicon and Oxygen having two different electronegativities, so the Silicon and Oxygen would not bond ionically. They are also from the same "side" of the periodic table, and not from two different sides like all of the other ionic bonds. Hope this helped!
