### Writing the hydrization

When asked what the hybridization is when do we have to write, for example, 2sp3 or just sp3?

I think it wouldn't hurt to specify the principle quantum number when you know what the central atom is. If you only know the areas of electron density around the central atom, then you can only discern the hybridization without the principle quantum number.

I think it's the same thing, but with the energy level, it's more specific for an atom.

Can you explain how to find the hybridization? I've always struggled with it

I would recommend looking at the example listed in 2F.3 (page 122 on the pdf). You should first identify the molecular shape about the central atom - the number of atomic orbitals it has is equivalent to the hybridized orbitals. A certain number of hybridized orbitals corresponds to a certain hybridization (which you can find on the chart on the same page). I highly recommend reading the text for further clarification.

The way I find hybridization is just counting the amount of electron densities around the atom in question. For example, if there are two electron densities, then you need an s-orbital and a p-orbital, so sp. Four electron densities would need an s-orbital and 3 p-orbitals, so sp3. Six electron densities would need the s-orbital, three p-orbitals, and two d-orbitals, so sp3d2. If you add the superscripts of your hybrid orbitals, it should add up to the amount of electron densities; just don't forget that the s-orbital counts as one!

Hello, I have a question about the difference between 2sp3 and sp3. How do you know if the "2" in front of the sp3 is supposed to be there? What's the difference between the two?

It’s the quantum number of the central atom when you’re talking about the hybridization of a molecule. Describing a molecule as 2sp3 and sp3 is saying the same thing.

Since we’re on the topic of writing hybridization, does it matter if we write d hybridization before s and p? Or can we out it after.

Since it is the quantum number then is it possible to write like 3sp2 or is it just up to 2sp3 (quantum number 2)?

The difference between 2sp2 and sp2 is the statement of the energy level (n=2), but unless the question specifies that the energy level needs to be stated, then its not required.
