And indicate the bond angles. How do you do that?

Um I'm sort of confused here. What is it asking me to do?

Like I have:

XeO4

I did the Lewis structure. And now it's asking:

A) # Of valence electrons (easy)
B) Steric Number (what's this?)
C) Electron Geometry (again, what's this?)
D) Shape (I know what this is, but do you guys have any suggestions how to do this easily? When I did the lab we were allowed to use molecular kits to build them.
E) Polar or non-polar.

Ah and it's also asking this.

Hybridization of the central atom and Sketch showing the overlap of orbitals

So we have

CO2

Lewis structure, simple. Valence simple. Then it asks hybridization, sketch showing overlap of orbitals, bond angeles, and # and type of bonds present (pretty simple)

I read my text, but the wording confusing me and everything is jumbled into different areas so it gets overwhelming to read it. If somebody could steer me in what I have to do, it would help alot.

Hey there, If you are to draw in 3D, use wedge, dotted line and line like the one often seen in stereo or organic chemistry.

As for steric number and electron geometry and shape(molecular geometry), can be easily googled. Just one comment, shape also known as molecular geometry can be predicted using VSEPR theory for covalent compounds. Also note that electron geometry might not necessary be the same as molecular geometry.

What are you confused about CO₂, its hybdrization?
