Answer:

Zero with the subscripts, +2 without them.

Explanation:

Hello!

In this case, since we consider that two silicon are bonded with four oxygen atoms to form silicon oxide according to the following chemical equation:

[tex]Si^{4+}+O^{2-}\rightarrow Si_2O_4[/tex]

It is also possible to realize it can be simplified to obtain:

[tex]SiO_2[/tex]

Which means that the total charge with the subscripts is zero, and without the subscripts +2 (+4-2).

Best regards!
