Question

If silicon has a charge of +4 and oxygen has a charge of -2, what is the total charge on this structure?

Answer 1

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:

$Si^{4+}+O^{2-}\rightarrow Si_2O_4$

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

$SiO_2$

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

Best regards!
