### How does an electrons's wave function change when it moves between energy levels?

You need to go back to the very start. Here, you're kind of asking: I have a solution $\psi_0$, how do I get the next solution $\psi_1$? The answer is to look at how $\psi_0$ was obtained, and it ...

### Why do different orbitals have different shapes?

The simplest answer is, of course, that this is what solving the equations produces, which is not that helpful. When the Schroedinger eqn. for the H atom is solved instead of using $x,y,z$ coordinates ...

### How does an electrons's wave function change when it moves between energy levels?

The Schrödinger equation is just a normal type of differential equation. We interpret it as describing how the operator for the sum of kinetic and potential energy (the Hamiltonian) produces the total ...

### Why do different orbitals have different shapes?

The Schrödinger equation You might be familiar with the following (magic) equation: $$\hat{H}\mathrm{\Psi} = E\mathrm{\Psi}$$ where $\hat{H}$ is the Hamiltonian operator, and $\mathrm{\Psi}$ is the ...

### Why are p orbitals most important for stability?

This question is legitimate, I do not know if this will be give a complete answer, but here is the basic principle. We have to define first the orbital at the outermost shell. When you have to solve ...

### What can visual observations of pi-bonding MOs explain about LCAO expansion coefficients?

I've thought that in N2, its symmetric so the expansion coefficients would be equal from the pi-bonding MO Yes, that's right; symmetric molecules have symmetric MOs which have symmetric coefficients ...

### According to molecular orbital theory, is the antibonding orbital empy when electrons are found in the bonding orbital?

Molecular orbitals are solutions of the Schrödinger time independent equation for a molecule. Some of these solutions lower the energy of the molecule (bonding molecular orbitals) and some raise the ...

### How does an electrons's wave function change when it moves between energy levels?

A quick intuition to understand how energy affects the position distribution can be obtained by looking at the s orbitals. For orbitals $1s, 2s, 3s, ..., ns$, the increasing principal quantum number ...

### Distance of Orbitals from Nucleus relation with Energy level and penetration power

I have studied that according to Aufbau rule the energy of subshells is dependent on the sum of $n$ and $l$ values. This would imply that the energy of subshells in a shell varies as  n_s<n_p<...

### Ionization Energy equal to single electron energy

The ionization energy is the energy deficit the bound electron has with respect to the energy of a free electron in rest. So, if the ionization energy of a $\ce{H}$ atom is $\pu{13.6 eV}$ and if we ...

### Why does the two OH bonds in H2O have different bond disassociation enthalpies? How does the bond cleavage happen here?

Two $\ce{OH}$ bonds in any molecule have different dissociation enthalpies, as only the first one is related to the original molecule. The second one is related to the original molecule with the ...

### How does the concept of the electron shell (also called energy level) and the orbital coexist?

There always coexist several models for historical and educational reasons. Especially the latter is based on several levels of trade off between accuracy and simplicity. If we take mechanical work: ...

### Confusion about the number of microstates for orbitals

I will explain in details why I stated (in the comments) that some states are inconsistent. The spin-orbit (S.O) coupling correlates the orbital angular momentum $\vec{L}$ and the spin angular ...

### Energy levels for H atom

Since (atomic) hydrogen has only one electron, there is no electron-electron interaction to differentiate internal levels. Of course, an energy level can be split if there is an external interaction. ...

### If the 2 electrons of a hydrogen molecule are more likely to be found between the 2 hydrogen atoms, why does this diagram says otherwise?

The shape of the orange blob is highly affected by the chosen contour level. In the image below, if you choose a contour level of 0.04, you get a oval much like the one shown. If you choose a contour ...

### In which orbital is the positive charge of central nitrogen present in diazomethane?

"Positive charge being present in an orbital" is weird formulation. Orbitals have zero charge at the best if empty. But as all 4 orbital pairs contributing to 4 bonds have 2 electrons, it ...

### Is p-bromophenol more acidic than p-chlorophenol?

I looked up the pKa values of each chloro- and bromophenol and compiled them in the following little table: pKa chlorophenol bromophenol ortho- 8.49 8.45 meta- 8.81 9.03 para- 9.14 9.17 (These ...
