How Do You Write the Electron Configuration for Si and O in SiO4?

Click For Summary
SUMMARY

The discussion centers on writing the electron configuration for silicon (Si) and oxygen (O) in the molecular structure SiO4. The correct electron configuration for silicon is 1s2 2s2 2p6 3s2 3p2, as it does not gain four electrons but rather has four valence electrons. For oxygen, the configuration is 1s2 2s2 2p4, indicating that each oxygen atom has six valence electrons in total. The participants clarify that SiO4 is typically represented as SiO4^2-, and emphasize that electron configurations should not be treated separately in molecular compounds.

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 SiO42-?

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 SiO42- are not ionic.

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