aman Posted December 27, 2003 Share Posted December 27, 2003 Does Uranium become a lot more stable when it is in a compound? Would it be possible to stablise some of the very heavy unstable elements made in Cyclotrons by quickly turning them into a salt?

YT2095 Posted December 27, 2003 Share Posted December 27, 2003 no, sorry, the electrons are all that get effected in a salt combination, the neutron count (instability) remains the same Link to comment Share on other sites More sharing options...
fafalone Posted December 28, 2003 Share Posted December 28, 2003 Stable uranium compounds do exist There's the CUO molecule I mentioned in a previous thread, and also (from WebElements): Hydrides: UH3: uranium (III) hydride Fluorides UF3: uranium (III) fluoride UF4: uranium (IV) fluoride UF5: uranium (V) fluoride UF6: uranium (VI) fluoride U2F9: uranium fluoride U4F17: uranium fluoride Chlorides UCl3: uranium (III) chloride UCl4: uranium (IV) chloride UCl5: uranium (V) chloride UCl6: uranium (VI) chloride Bromides UBr3: uranium (III) bromide UBr4: uranium (IV) bromide UBr5: uranium (V) bromide Iodides UI3: uranium (III) iodide UI4: uranium (IV) iodide Oxides UO: uranium (II) oxide UO2: uranium (IV) oxide UO3: uranium (VI) oxide U2O5: uranium (V) oxide U3O7: uranium oxide U3O8: uranium (V, VI) oxide U4O9: uranium (IV, V) oxide Sulfides US: uranium (II) sulphide U2S3: uranium (III) sulphide Selenides USe3: uranium (VI) selenide Tellurides UTe2: uranium (IV) telluride UTe3: uranium (VI) telluride Nitrides UN: uranium (III) nitride U3N2: uranium nitride U2N3: uranium nitride ..the oxides are very stable, and uranium hexaflouride is generally stable in normal atmospheres.

aman Posted December 29, 2003 Author Share Posted December 29, 2003 Another out of the box approach. If we took pure Uranium and put it into orbit around neutron star at an incredible speed, would we reduce it's decay relative to us and later knocked it out of orbit with another load, would it seem to have been stabailized for the period of time it orbited?

Cheetah Posted December 29, 2003 Share Posted December 29, 2003 If I understand your thought correctly, isn't that a question of relativity? If the uranium moves at near light speed, and time then slows down, I would expect it to decay slower than uranium on Earth. Though it would only seem to have stabilized if it moves fast enough and for a short enough time for it not to decay. Though I still don't understand what the neutron star has to do with this, so maybe I completely misunderstood your question Link to comment Share on other sites More sharing options...
YT2095 Posted December 29, 2003 Share Posted December 29, 2003 Faf sure there are stable U compounds, but an unstable U isotope will not become more stable when made into a salt was my point otherwise, you may treat stable U isotopes as any regular metal, the electron bonding does not affect the Nucleus however Link to comment Share on other sites More sharing options...
fafalone Posted December 29, 2003 Share Posted December 29, 2003 The 238U isotope (unbounded) has a halflife of over 2000 years I'd have to call that stable tho Link to comment Share on other sites More sharing options...
YT2095 Posted December 29, 2003 Share Posted December 29, 2003 ok, my point is that making ANY U salt will still have the same instability as the original U metal. making it into a salt will not make it more stable as an isotope (and I think that`s what he was after in the 1`st post). the salt will be just as unstable as the metal. it maybe CHEMICALY stable sure, but it`ll not make it any the less radioctive Link to comment Share on other sites More sharing options...
aman Posted December 29, 2003 Author Share Posted December 29, 2003 What made me wonder about the stability being effected by electrons was the fact scientists will ionize krypton to make it less stable in Cyclotrons so it will free its protons and nuetrons easier. I am just suggesting the reverse might be true and a U238 salt might have a half-life of 2000+ years because the electrons might have an effect on the protons which might then effect the neutron configurations. I couldn't find any data. Maybe cooling it to 1deg K might have an effect on decay. I wish I had a lab. Thanks for all your help.
