    So... stupid fantasy question: if we could control the process and stop it when we want could we achieve the alchemist's dream of turning lead into gold?

      Actually yes, with the right equipment you can basically make any atom into another, in this case that you are saying lead is 82 protons and gold is 79 and if you Can somehow make 3 of the protons in for example neutros using gama decaying you’ll end up with a gold atom. The problem is that making atom by atom is an extremely un efficient method and at the end you end up wasting more resources and energy than the value you end up gaining in gold.

      Radioactive decay cannot be controlled. It happens when it happens.
      However, nuclear reactions like fission and fusion can be controlled because they depend of the right pieces coming together. But that’s more useful for producing energy than gold.

    What makes them unstable. You mentioned because they're heavy and then you mentioned that there's also unstable ones that are not heavy. I don't get the actual reason 😅? Is it because of the ratio(protons/neurons) for both heavy and none heavy nucleus?or there's something else?

      I am no expert, but I assume the ratio of protons to neutrons is the cause of the instability of the nucleus.

    • @yummynyx4069

      Based on what he said, I think it is a combination of both. It is unstable because of a heavy nuclei or/and the ratio of protons and neutrons.
