Answer:

The answer to your question is polar; polar

Explanation:

First, we must consider the following information

                      Type of bond               Difference of electronegativity

                       Ionic                                   > 1.7

                       Polar covalent                  between 0 and 1.7

                       Nonpolar covalent           0

Then, we must determine the difference of electronegativity of this molecule

                        SiCl₄ = 3.0 - 1.8

                                 = 1.2

So, this molecule has a polar covalent bonding and the molecule is polar.
I believe what the answer could be is Polar; polar!
