Electron shell jumping

[sunshaker]

I believe elements have not always had the same electron sequences,

 

Has i have tried to show here: http://alphaomegadotme.files.wordpress.com/2013/02/grouped-elements-old-quarkstargalaxyuniv.xls ,

fig 1/2 are what i believe they where at one time, In fig 3, Shows what they are now believed to be, the difference between past/present electron seq is shown in purple,

 

At this present time Sulphur has an electron sequence of 2 8 6, But i was wondering what effect would occur to sulphur if the electron seq jumped to 2 9 5?

 

Also aluminium 2, 8, 3 to 2, 9, 2?

That change is not possible. Inner L shell is filled and can't accomodate more than 8 electrons. L shell has 2s and 2p orbitals which can accomodate 2 and 6 electrons respectively in total. Electronic configuration has varied because we have learnt new ideas and unlearnt some. Nature is as it was.

I asked this question after coming across this article: http://chemistry.about.com/od/chemicalbonding/tp/Exceptions-To-The-Octet-Rule.htm

 

And reading this about Forbidden mechanisms: http://en.wikipedia.org/wiki/Forbidden_mechanism

 

And as valence electrons have the ability to absorb or release energy in the form of photons and jump shells, What happens to valence electrons in elements like sulpur and aluminium when their valence electrons release energy.

I think you're talking about two different things. Filling levels and shells assumes the system is in the ground state. Photon absorption and emission, where the selection rules mentioned in the second link come into play, involves excited states.

I am looking at excited states, I came across this when looking for exciting single atoms with lasers:https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&uact=8&ved=0CFAQFjAE&url=http%3A%2F%2Fwww.extremetech.com%2Fextreme%2F176063-this-single-atom-engine-breaks-the-laws-of-physics-could-drive-progress-in-quantum-computing&ei=qFsoU9WdK6SS7AakvYDIBw&usg=AFQjCNFmyaVaIKArt1BihPUqC9S3xJfzyw&sig2=Kxz6b0GX1lzwmcwN9vAp1g&bvm=bv.62922401,d.ZGU

I was also wondering why they use calcium electron seq 2 8 8 2? why not magnesium 2 8 2? is there a reason for calcium?

Also in one of my posts about iron which is 2 8 14 2 could this technique/or similar be used to excite an iron atom to 2 8 8 8?

Electron shell jumping is an interesting phenomena of the Quantum world and one that interests me from the point of view of light (photon) passage. The interesting idea of the excited electrons in the calcium atom propulsion sequence was the colour of the 'agitated electrons' thus the photons given off. I would be interested to hear of any experimentation that associates atomic elements with laser excitation (to cause electron valence shell jumps) and the differences in photon colour generated as a consequence of the element atom stimulated. Likewise the phonon emissions and the possible detection of the heat magnitude for the different atomic elements.

That's called spectroscopy, and it's a very wide field of inquiry. especially now that there are several types of lasers on can use. There are a lot of transitions to investigate, and multiple tools used to do so.

 

You should probably open a new thread with more specific questions. The basic structure of atoms is well-understood via quantum theory.

According to Bohr-Bury rules, an electron shell can have the maximum number of electrons as [math] 2n^2 [/math], where n is the energy level number. Exception is that the outermost valence shell can have not more than 8 electrons and the shell preceding it not more than 18 electrons.

If you look at the periodic table, you will notice that this rule preserves the order and regular pattern of the elements.
