Alchemy can you make gold

In certain atoms, the nucleus is radioactive and unstable, a property usually linked to the number of neutrons in the nucleus. A radioactive atom stabilizes only after emitting energetic radiation, which is sometimes accompanied by conversion of one type of subatomic particle into another, such as protons to neutrons.. Energy production in nuclear reactors is based on nuclear fission, where radioactive uranium breaks down to lighter elements, including xenon and strontium.

Gold will cost a lot more money. British scientist Frederick Soddy, a radiochemist pioneer. By accelerating a neutron beam to a speed close to that of light and projecting it on a metal sheet, protons can be torn out of metal atoms and turned into atoms of other elements. The age-old vision of alchemists was revived in the s, when researchers used this method to make gold atoms from mercury, whose atoms have one more proton than those of gold.

Similarly, in , other researchers made gold from bismuth, which has four more protons than gold. However, this success was mostly theoretical, because the amount of gold created in these experiments was small.

Furthermore, the gold created was mostly radioactive, so it was dangerous to humans. Chemical reactions change the number and shape of the electrons in an atom but leave the nucleus of the atom unchanged. The ancient alchemist dream of creating gold by simply reacting chemicals is therefore impossible.

You have to use nuclear reactions to create gold. The difficulty is that nuclear reactions require a lot of energy. The nucleus of a stable atom is very tightly bound together, so it is hard to get anything permanently into or out of the nucleus. To induce a nuclear reaction, we have to shoot high-energy particles at a nucleus. We can get such particles either from radioactive decay, from nuclear reactions in a reactor, from the acceleration of slow particles, or from a mix of these techniques.

For example, Sherr, Bainbridge, and Anderson created gold in by shooting neutrons at mercury. The amount of gold produced was so small that Morrissey and his colleagues had to identify it by measuring the radiation given off by unstable gold nuclei as they decayed over the course of a year. In addition to the several radioactive isotopes of gold, the particle collisions presumably produced some amount of the stable isotope gold —the stuff of wedding bands and gold bullion—but because it does not decay the researchers were unable to confirm its presence.

Some of the collisions would be expected to remove three protons from lead, or one proton from mercury, to produce gold. Glenn Seaborg, who shared the Nobel Prize in Chemistry for his work with heavy elements and who died in , was the senior author on the resulting study.
