thnx

It's point group symmetry is the same as for methane: Td

Yes, that is definitely true. I guess my point is that it is not the quantum numbers which are not well understood. It is the atomic properties can't be simply explained in terms of quantum numbers alone. One have to apply additional principles such as "Aufbau principle", second periodicit...

Schrödinger equation for a system have multiple solution.
Quantum numbers are a way to enumerate these solutions.
But those quantum numbers to which general chemistry textbooks refer to are taken from a simplified model of hydrogen-like atom, rather than a real atom.

That is pretty amazing indeed! Reading the website I would like to contest the following: quantum numbers n, l, ml and ms , that describe electronic populations of the atoms, are not completely understood in terms of mathematics Quantum numbers are result of an exact solution of the non-relativistic...

Hello Lorenzo,

Thanks for the archive - it's quite interesting!
I've just published full text of my review here:

And now the solution has been posted:
Aharonov-Bohm effect (solution)

What do you mean by EIS, Electrolyte-Insulator-Semiconductor?

Light emitted from atoms correspond to transitions between energy levels an therefore measuring the energy of emitted photons allows one to obtain energy levels.

I think that Pb product should be different, namely PbSO4.
And the overall equation:

thanks alot, i wish i was in college...but this is just high school chemistry. And i wish i was in college...be so awesome. Also im from texas. Alright i have another for anyone to answer.... Write a balanced equation for the complete combustion of each compound. butene(C4H8) octane(C4H18) glycerol...

Aharonov-Bohm effect is one of the most fascinating discoveries of the 20th century. Did you know about it?
Typical problem where Aharonov-Bohm appear: Aharanov-Bohm effect.
Your comments are welcome!

Q1: Becuse there are different copper chlorides. is copper (II) chloride
and is copper (I) chloride

Q2: No, that only means that they have the same absolute values of charges.
