Is it basically wrong? It just seems like hand-waving...
I'm talking about an s orbital and 3 p orbitals nicely combining to make nice convenient orbitals which happen to point outwards tetrahedrally. I don't see how that works.What do you mean?
afaik, orbital hybridisation is pretty much how it works. You got a space of probability where you can find an electron or set of electrons. The electron(s) in question is/are essentially everywhere in that cloud at once. It's like a probability cloud.
All that stuff about neat, circular orbitals is what's wrong.
