Electron Config: Si and O for SiO4

[pearapple]

Homework Statement

Write the electron configuration for SiO₄.

Homework Equations

The Attempt at a Solution

My professor said we just need to show the configuration for Si and O separately.

I think Si gains four electrons, so its configuration is 1s2 2s2 2p6 3s2 3p6

But Oxygen I'm not sure about. Each oxygen only gains one electron, so would it be

1s2 2s2 2p5?

It's been a loooong time since I did chem and I can't remember how this works. Am I doing this right?

It doesn't make sense. First of all - no such things as SiO₄. Shouldn't it be SiO₄^2-?

Then - there is no such thing as separate configurations of atoms in a molecule. In ionic compounds you can write electron configuration of ions, but bonds in SiO₄^2- are not ionic.

Sorry, I have no idea what your prof is asking for.
