Hello,

I have no objections to the contents of the "Electron density" article, but I think it would be more meaningful to start with a macroscopic definition, i.e. number of electrons per unit volume. This could then be related to the probabilistic definition of density, and the current contents could be introduced by a discussion of when the macroscopic view breaks down.

The reason I'm suggesting this is that there is currently a link from the article on incoherent scattering, where it is mentioned that this technique is used to measure electron density (in this case, the number density of free electrons in near-Earth space is intended) while the linked article talks only about orbitals in molecules.

Merging electron density with electronic density[edit]

Hi all. I propose to merge those two articles as their subject is strictly the same. Faithfully yours Grimlock (talk) 21:01, 1 September 2010 (UTC)

  • I am not really sure about the wisdom of doing this, but if it is going to be done, which way do you want to do it? I suggest electronic density to electron density. If you agree the merge tags should be changed to mergeto and mergefrom tags. --Bduke (Discussion) 22:53, 1 September 2010 (UTC)
You may be right, but there are at least some links to these pages, e.g. on Saha ionization equation and Ionized air glow, that use "electron density" in a different (classical statistics) sense. Such links should be looked for and removed. Art Carlson (talk) 10:47, 2 September 2010 (UTC)
I agree with both of you. For the links pointed by Art Carlson, I underlined that this classical view is used in plasma physics, and perhaps this should be distinguished in another page. Dealing with this in electron density (as it is understood in quantum physics and chemistry) is misleading, in my mind. Grimlock (talk) 19:34, 2 September 2010 (UTC)
