I'm trying to get a much better grasp on atoms and molecules and I am a visual learner. I found the above image here. This intuitively makes sense to me because I can see how the electron orbitals change from a spherical shape to a tear drop shape after this process:
Now the hydrogen electron clouds have become trapped inside the oxygen atom because they can't overcome the repulsion of the outer oxygen electron clouds.
The exposed hydrogen protons help me understand how H2O is a polar molecule because they give the two "corners" of the molecule a positive charge and the opposite side of the molecule a negative charge, corresponding to this model of H2O:
My question is, does the first model above actually represent the physical layout of the nucleus's and electron clouds of an H2O molecule (as best we understand it currently)?
It looks like the orbitals in the first picture above may be a bit off on the oxygen molecule since there should be two spherical shells around the oxygen nucleus (1S and 2S) with 2 electrons each and then the other 4 electrons would occupy (but not fill) the 3 2P double-teardrop shells on the X, Y, and Z axis (although I'm not sure why one axis of the 2P shell is smaller than the others). But barring that perceived discrepancy, the 4 valence electrons would exist in the teardrop shaped 2P orbitals, correct? That would make sense to me then how the hydrogen electron orbitals could get trapped behind them.
( I used this electron orbital diagram for oxygen for reference:
