could anyone tell such a method how one can make stable lead from stable bismuth?
No, pure stable isotopes are not. If you extract hydrogen from Evian mineral water, it is no more radioactive. The time it takes the water to percolate through the Alpes mountains to the source (23 years, I think) is long enough for all traces of tritium to have disappeared. (I have no shares of this company).cesiumfrog said:Isn't everything slightly radioactive?

But I think that the question posted was something as "If you bombard bismuth with protons, will it transform in lead?". I do not know the aswer.
cesiumfrog said:I wasn't originally referring to mixtures of isotopes. Even the proton itself is thought to have a half-life, though the decay hasn't ever been observed yet. If you wait long enough, isn't it a quantum certainty that lead will start changing to iron?
Is something radioactive when you can't detect any radioactivity?cesiumfrog said:I doubt that. In the context of exponential decay, "all traces" sounds too strong. Nonetheless, I wasn't originally referring to mixtures of isotopes. Even the proton itself is thought to have a half-life, though the decay hasn't ever been observed yet. If you wait long enough, isn't it a quantum certainty that lead will start changing to iron?

If I do not detect something, the only thing that I can say is that I have not detected it and say that if the something exists, its magnitude o probability is less than the sensitivity of my system. But I cannot say "well, I don't see a thing, but it exist".cesiumfrog said:But you are making this philosophical. Just because *you* don't have a sensitive enough detector to distinguish two things does not mean those things are equal.
People of 19th century could not say that there where or there where not radioactive materials. If a theory of radioactivity had been proposed, the only thing that could be asserted at the time is that no radioactivity had been detected yet.vanesch said:The problem with this definition of radioactivity is then that it depends on the experimental technique to verify it. This would mean, for instance, that before the 19th century, there were no radioactive materials (as one couldn't detect it at that time, or recognize it as such).
lpfr said:The only thing you know is that, for now, they have not been detected. It doesn't mean that they do not exist. It just means that we don't know and we can't assert either that they exist or the contrary.
You could have done the predictions and the bayesian plausibility for Newton laws for speeds bigger than c before Michelson and Morley experiment.cesiumfrog said:Moreover, sometimes a theory is so well tested that we can have good reason to believe even those predictions that we are not yet able to test. (This is quantified using the science of Bayesian plausibility.)
To expand on what I wrote above:Thaakisfox said:All this is nice, but there arent any suggestion to my original problem. Someone please
cesiumfrog said:Yes, you should be able to do it very simply: by hitting a bismuth target with a proton beam (accelerated hydrogen ions). Some (probably incredibly small) fraction of bismuth atoms should absorb two protons in succession, then beta decay (changing one proton to a neutron), transforming into your desired lead atom.
lpfr said:I think that you wrote this without having a look at the periodic table. It is the other way. You must take out a proton and a neutron to transform bismuth to lead.
The process of making lead from stable bismuth is known as the Kroll process. It involves heating bismuth with carbon and iron to produce lead.
The materials needed for making lead from stable bismuth include bismuth, carbon, iron, and a heat source.
Some safety precautions when making lead from stable bismuth include wearing protective gear such as gloves and goggles, working in a well-ventilated area, and disposing of any leftover materials properly.
No, only specific types of stable bismuth can be used to make lead. It is important to use high purity bismuth with low levels of impurities for the best results.
The lead produced from stable bismuth can be used in various applications, such as in batteries, ammunition, and as a component in soldering. It can also be used in the production of other materials, such as glass and ceramics.
