4.26

Write the Lewis Structure and determine whether the molecule is polar or nonpolar.
SiO2

I got the Lewis Structure but am unsure what property makes it polar/nonpolar?

In a molecule, nonpolar atoms tend to have a low difference in electronegativity while polar atoms tend to have a high difference in electronegativity. Also, electrons in a nonpolar molecule are shared equally while electrons in a polar molecule are shared unequally, creating a dipolar moment.

^ Just to add on, a molecule composed of two of the same atom has a nonpolar bond, since the electronegativities are the same (electronegativity difference is 0) and the electrons are shared equally.
