Thread: Atomic models... WICH?

Ok, I have read a couple of articles about a new atomic model...

The link to the model above was said false because they said that electrons did not "circle" perpetuously around the nuclei

Instead, as you will see in the link below, they said that this atomic model was more like it.

I understand out of this that electrons "vibrate" arround the nuclei of the atom instead of "turning" arround it... Is this what it is or is the electron spinning arround the nuclei of an atom?

its rather the electron goes around the nuclues wich such enourmus speed. But you can onl calcualte the probebility if finding the electron at a certain point from nucleus. So the last picture is right since its a picture showing this chance visualy.

Well thank you, that clarified it quite alot.

My understanding is that you shouldn't think of the electron as a particle whizzing around a nucleus at all. It's not that the electron is travelling really fast, the electron actually exists at ALL positions simultaneously, like a 'cloud' of negative charge.

In the second picture that LEAP posted the two lobes at the top and bottom are not continuous with the left-right lobes. An electron does not jump between them, it exists partially in both 'parts' of the orbital at the same time.

It's like the famous 'double-slit' experiement, where if you fire a single electron it actually passes through both slits simultaneously:

They're crazy these electrons.

I prefer the model that supports the electron as a 'cloud' or ring around a nucleus, which 'morphs' into an energy sphere when passing between atoms. It 'jumps' to a higher energy band by absorbing energy which effectively lengthens the cloud belt and promotes it to the higher energy level, when the cloud snaps back to its original size it ejects a portion of itself equal to the energy of a proton. This was proposed in order to overcome the standard model which suffers from electron unbalance.

i agree with all of you. was just saying it like that to make it easier to understand
