OK!!! But your question is a nuclear physics problem. And it's only used in the lab. No practical value. The significance of saying this is not to make money, but to research nuclear physics.
-
Before and after a chemical reaction, the species of the element does not change.
If there is no gold in the reactant, then the product is not likely to have gold either, and gold is elemental.
However, modern science and technology can use atoms as bullseyes and bullets in specific environments, similar to nuclear reactions, to generate new elements.
You say that someone has turned mercury into ** now, but the cost is extremely high. Even if he could, how high would it cost? Do you want to build a nuclear reactor? If the cost is not outrageous, will he himself give this technology to others?
So, I don't think you should believe that.
Give you an alternative way. In our photo studio, the development and fixing waste liquid used for photo processing contains mercury, silver and other metals, which can be used through certain technologies.
-
Theoretically, it is possible, for example, to make an element with a higher atomic order than gold lose one or more neutrons, so that it becomes an element with atomic order 79.
-
Theoretically, yes, but the conditions are very demanding. And it requires heavy elements (more expensive than gold).
-
I can tell you responsibly that you have been scammed.
I don't dare to say that it won't be possible in the future.
However, under the current technical conditions, it is not possible to arbitrarily change the nucleus.
-
From an atomic point of view, it should not be.
If someone wants to sell you that technology, congratulations, you've won.
It's better to turn graphite into diamond.

The formation process is as follows: when the ore Pisson branch contains natural gold, the gold is hidden in the rock in the form of granularities or microscopic particles, usually at the same time as quartz or sulphur-burning sensitizer veins such as pyrite. These are called lode, or gold.
Natural gold also occurs in the form of leaves, granulars, or large nuggets that erode out of the rock.
The sand and gravel that eventually forms alluvial deposits is called placer, or alluvial gold. Alluvial gold is bound to be richer than the surface of veined deposits, because the adjacent minerals of gold in the rock are oxidized, weathered, cleaned, and then flowed into rivers and streams, where they are collected and combined to form nuggets.

Iron atoms above silver can also be fused, but energy absorption is required instead of energy release. Silver is neither fusion nor fission. There are two ways for heavy elements above iron to be generated, the lighter ones can be made by supernova explosions, and the energy provided by supernova explosions causes the elements to coalesce into heavy elements above iron (the gold and silver ornaments we use today are all from early nova explosions).
However, most of the radioactive materials with plateau subordinal numbers are not able to provide such high energy in the existing universe (nearly 10 billion degrees), so they are all formed at high temperature and high pressure in the short term after the big **.
-
Gold is formed at the end of stellar evolution. Stars of general mass, such as the Sun, after going through the long evolutionary stage of the main sequence star, the nuclear fuel reaction is exhausted, and the nuclear reaction elements are formed: Hhe C, O, and finally Fe.
The nuclear reaction before iron releases energy, and the subsequent reaction absorbs energy, so the spontaneous nuclear reaction stops after that and the white dwarf phase is reached. At this stage, the gravitational pull of the star collapse is overcome by electron degeneracy pressure.
In a white dwarf star with a mass of the Sun (i.e., the "Chandrasekhar" limit), the electron degeneracy cannot resist its own collapse, and the electrons are pressed into the nucleus. When the outer layer collapses violently and touches the inner core of a neutron, it is a supernova explosion. It is at this time that the metal element heavier than iron is formed, and the remaining core is a neutron star.
-
Many elements, including gold, come from the planet**. Of course, the gold element comes from neutron stars, and the quake we know as Thor's hammer also comes from neutron stars. Doesn't it feel like it's magical?
-
To be precise, all substances are formed after the big **. That is to say, after the occurrence of large **, in the process of reorganization and change of matter, gold elements and heavy elements are formed.
-
All kinds of elements probably come from the collision between protons and neutrons, because their existence is not particularly stable, so it is also very difficult to capture them, probably at the moment of collision.
-
This is from fusion.
Take nuclear fusion, for example. This is a complex process that can only be achieved by a strong gravitational pull, and only by massive planets, otherwise only iron can be formed.
-
All elements are substances that can be stably formed by atoms and protons in the process of colliding with each other, of course, the stability of matter is relative, and it can also become an unstable state after environmental changes.
For NM500 wear-resistant steel plate, the chemical composition is more worthy of analysis. In fact, the traditional wear-resistant steel used in construction machinery is generally high manganese steel, although high manganese steel has the performance of work hardening, but it has a strong hardening ability after being subjected to impact stress during its use. Due to such a reason, it can only play its role under a large impact load, and the wear resistance of its hardness can not be improved for the working condition that the impact load is not large, in this case, the yield strength of high manganese steel is not high after work hardening, and the workpiece sometimes cracks when under the action of a large force, and it is difficult to achieve the expected service life, which is a fatal defect for machinery. >>>More

If you like to wear some floral skirts, or some clothes with floral elements, you can add some plain colors on top, for example, you can add a white jacket on top when you wear a floral skirt, or if you like to wear floral shirts, you can wear a light-colored pants or skirt underneath.
Yes, this is equivalent to creating an array of objects, and each element of the array is an object, so the methods of that object can also be used by subscripting. However, if you put objects in array a[10], you need to make sure that the type of array a[10] is the same as the type of the 10 objects you put in. Such as: >>>More
Summary. You can put the elements of both arrays into one array and then use the sort() function. >>>More
