How to convert baser metals into precious metals? Ncert class 11 Chemistry...Pls help me guys soon... The best answer will be marked as "Brainliest"!!!

Yes, the process is called Nuclear transmutation .
Nuclear transmutation involves the conversion of an isotope to a completely different element .
A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside cause is needed.
Artificial transmutation may occur in machinery that has enough energy to cause changes in the nuclear structure of the elements. Such machines include particle accelerators and tokamak reactors. Conventional fission power reactors also cause artificial transmutation, not from the power of the machine, but by exposing elements to neutrons produced by fission from an artificially produced nuclear chain reaction. For instance, when a uranium atom is bombarded with slow neutrons, fission takes place. This releases, on average, 3 neutrons and a large amount of energy. The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted. This is called a chain reaction.
Infact in nature ,-
Elements heavier than iron, such as gold and lead, are created through elemental transmutations that can only take place in supernovae - as stars begin to fuse heavier elements, substantially less energy is released from each fusion reaction, and each fusion reaction that produces elements heavier than iron is endothermic in nature, and stars are incapable of carrying this process out anymore, therefore theses metals are precious and relatively less abundant in nature .
