What is the VSEPR shape of Si02? Also, is it polar or non-polar and how do you tell?

By drawing the Lewis Structure, you will see that the most stable structure is O=Si=O. The electron arrangement and molecular shape are both linear. Since SiO2 has two places of electron concentration and no lone pairs, it is linear.

Since the electron arrangement is linear and on either side of the Si are 0 atoms, the dipole moments cancel (dipole moments are formed when there is a difference in electronegativity between the two atoms). this means the molecule is non polar.
