SiO2 is covalent because the difference in electronegativity is not great enough for it to be considered ionic. Ionic compounds have a difference in electronegativity of greater than 1.9

The Answer above is not right. SiO2 is Covalent. correct, but ionic compounds have an electronegativity difference of 1.7 or higher, not 1.9.
