[edit] Failed AFD

This article had a failed AFD. Anyone who still thinks this article should be merged is free to take the editorial decision to do so. Johnleemk | Talk 09:27, 30 November 2005 (UTC)

[edit] removed text

I have removed the following section, because it erroneously ascribes to element 136 properties which actually belong to element 137. The correct physics of element 137 is correctly described in the article on untriseptium. The claim in question is that this is the last element that would be stable according to the Schrödinger equation -- they can't both be the last stable element! One of the two articles must be wrong!

The remainder of the paragraph (the part about absorbing 137 photons, etc.) appears to originate in the reference Feynman Online, whose contents are ineligible for the Wikipedia on the basis of the policy excluding material that is original research and unverifiable. If anybody wants to restore this material, let them first cite a reputable source for the claims contained in the deleted paragraph.

[edit] Significance Please help improve this section by expanding it. Further information might be found on the talk page or at requests for expansion. Classical physics indicates that element 136 would be the last chemically stable element. This is because element 137's electrons are predicted to move at the speed of light itself. This is because electrons and protons are bound together through electromagnetic force, which is carried by photons. The odds that an electron will absorb a single photon are 1/137. As there are 137 protons in element 137, there are 137 photons produced, yielding a 100% absorption rate. Therefore a ground-state electron in element 137 will orbit at the speed of light. This does not necessarily indicate that an electron orbiting at the speed of light would lead to chemical unstability of the atom, rather the atom would border between stability and unstability. As the nature of the central charge does not feature in the calculation of the result above, if it were possible to have an alternative object as a central charge; for instance a small, charged black hole (allowed under modern physics) forming the core of an atom, it could not have a charge of greater than -137 times that of the electron.

[edit] AfD?

I would tend to think that this article has no reason to exist. It is about an element that has never existed, and though it may exist at some point in the future, at this point the article has no useful information. The atom has no significance, making this article useless. But, instead of just putting it up for a vote, I thought I'd make sure there isn't something that just isn't on the page yet. I'm not a physicist; there may be something about the element 136 that is important, but the article doesn't say anything. Heavy Metal Cellist^talk_contribs
