alpha-chloropyridine

The main uses of α-radon are in the fields of medicine, scientific research and industry.
In the field of medicine, the α particles generated by the decay of α-radon have strong ionization ability. Doctors can make good use of this property to treat specific diseases, especially for some tumors. The principle is that α particles can precisely destroy the DNA structure of cancer cells, making it difficult for cancer cells to proliferate and survive, but have little damage to surrounding normal cells. Just like the "Tiangong Kaiwu" said, "Each thing has its own use, and if you use it well, you will benefit life". Accurate treatment can achieve the purpose of curing and saving people.
In scientific research, α-radon is also an important research object. Due to its stable decay characteristics, it can be used as a natural clock to help researchers determine geological age and trace paleontological remains. By analyzing the proportion of α-radon and its decay products in rocks and fossils, scientists can infer the events of the past, just like exploring the key to the mystery of history, just like the exploration of the laws of all things in the world in "Tiangong Kaiwu", revealing the evolution of the earth.
At the industrial level, α-radon can be used to make special detection equipment. Because of its radioactivity, it can keenly sense specific substances or environmental changes, and is widely used in non-destructive testing, safety monitoring, etc. For example, to detect subtle defects in industrial materials and ensure product quality, just like the pursuit of technological excellence in "Tiangong Kaiwu", to ensure stable and reliable industrial production. Alpha-radon, with its unique properties, plays an important role in the fields of medicine, scientific research, industry, etc. However, its radioactivity also has potential hazards. When applying, it should be treated with caution and used rationally to obtain its benefits and avoid its harm.

Alpha-radon is radioactive and inert, with the following physical properties:
- ** color **: Under normal conditions, radon is the color of the color. However, at low temperatures, radon will become colorized, and the temperature will drop to about -100 ° C. Radon will condense the light liquid, and the color will gradually deepen, until it solidifies the bright crystal at about -211 ° C.
- ** Density **: Its density is 9.73kg/m ³, which is much heavier than the air, so it tends to sink in the air, and it is easy to gather at low temperatures, such as basements and bottom wells.
- ** Melting temperature: -71 ° C, -61.8 ° C, low melting temperature, because radon is an atomic molecule, and the molecular force is weak.
- ** Solubility **: Soluble in water at 25 ° C, 100 ° C water can dissolve radon as large as 1.09 ° C. It has greater solubility in some solvents than in water, such as 10 times the solubility in benzene water.
- ** Radioactivity **: The most important physical property of radon is that it is radioactive, it does not emit alpha particles, beta particles and gamma radiation. Its decay compounds are also radionuclides, such as - 218, - 214, etc. The half-life of radon-222 is 3.82 days, which means that every 3.82 days, half of a given amount of radon is lost. Radioactivity makes radon and its offspring dangerous, and exposure to radon can lead to diseases such as lung cancer.

Alas, if you want to study whether the chemical properties of α-deuterium are stable or not, this needs to be reviewed in detail.
The stable change of the properties of various things in the world is related to the disturbance of the internal structure and external forces. Alpha-deuterium, the genus of atoms, is composed of protons, neutrons, and electrons. The protons and neutrons in the nucleus of the atom are intertwined with each other, just like the state of intertwined forces.
Internally, protons are positively charged, neutrons are neutral, and the two coexist in the nucleus. The ratio of their numbers affects the foundation of α-deuterium. If the ratio is just right, the force in the nucleus is balanced, and the core of α-deuterium is stable, its chemical properties will also become stable.
As for external forces, changes in temperature and pressure are all factors that cannot be ignored. Under high temperatures, atoms are very active, like trapped beasts trying to get out of their cages, frequent electron transitions, or chemical bond clutches; under high pressure, the atomic spacing is approaching, the interaction intensifies, and the original equilibrium of α-deuterium is impacted, and its chemical properties change accordingly.
Furthermore, the environmental medium in which α-deuterium is located can also affect its properties. In an active medium, α-deuterium may be excited and react with other substances, just like entering a dye vat and changing color; in an inert environment, α-deuterium is like a paradise, relatively stable and difficult to react.
In summary, the chemical properties of α-deuterium are stable or not, and it cannot be generalized. The internal structure, the external temperature and pressure, and the environmental medium are all like wire winding, which together determine the stability of its properties. When all internal and external factors are suitable, the properties of α-deuterium may be stable; if a certain factor is out of balance, its properties may also change.

The production process of α-deuterium, although ancient times did not have this name, it can also be similar to the art of inferring ancient times with today's intention.
The various techniques described in "Tiangong Kaiwu" all follow the principles of nature and are in line with the method of creation. If the production of α-deuterium is discussed in terms of ancient methods, the three processes of sourcing, refining and purification should be the main ones.
Those who obtain materials must find their source between heaven and earth. Alpha-deuterium, the isotope of hydrogen, can also be found in water. Water, the source of all things, contains various isotopes of hydrogen. The wise men of ancient times, although they did not know the name of α-deuterium, knew the mystery of water, and began by taking water, they must carefully investigate its source, and find clear and pure water, which is the best.
The method of refining should be the technique of combining fire with things. In ancient times, fire was used as the source of heat. Although there are other methods today, they should use the ancient meaning to measure it, and control the temperature of fire so that it does not slow down. Or you can add medicinal stones to help separate. For example, the method of smelting in "Tiangong Kaiwu" uses the combination of stones and minerals, and uses the power of fire to separate the minerals. In the refining of α-deuterium, it is also necessary to find something suitable, and smelt it together with water, so that α-deuterium gradually emerges.
The purification work is particularly fine. In ancient times, purification was mostly by methods such as lustre, steaming, and filtration. For lustre, remove its dross; for steamer, take its essence; for filter, make it clear and turbid. For α-deuterium, multiple methods of lustrous steaming should be used to gradually remove impurities, and the purity will rise. For example, in the method of salt production, seawater is evaporated by the sun, then leached and braised, and fried to obtain refined salt. The same is true for the purification of α-deuterium, which is repeatedly steamed to achieve a high purity state.
Although the techniques of ancient and modern times are different, the principles are the same. Based on the essence of "Tiangong Kaiwu", the production process of α-deuterium must be based on nature, and the law is based on ancient times and not limited to ancient times, in order to obtain its wonders.

Nowadays, those who have alpha-neon orientation are sincerely remembered by everyone in the field of price in the market. Looking at the description of "Tiangong Kaiwu", although the price of alpha-neon is not detailed, the ancient discussion of things is mostly about use and thickness, and the two are of great importance in price.
In terms of use, the use of alpha-neon is either related to lighting or related to the field of scientific research. If lighting, its light is special, it can be a special scene, and it can make the city shine. Therefore, if it is widely used, its price must not be cheap. In scientific research, alpha-neon may be an important item for experiments. Research assistants explore and know it in detail, and its achievements are great, which can also increase its price.
As for purity, if α-neon is rare in the world, it is difficult to collect and difficult to obtain. The so-called "rare things are expensive", its price should be high. If it is produced in large numbers and easy to obtain, the price may be flat.
In this world, science and technology are advancing day by day, and the awareness of α-neon is becoming deeper and more widely used. The price of α-neon in the city may vary from time to time and change according to demand. Roughly speaking, if it is used for high-end scientific research and the output is limited, the price may be as high as a thousand gold; if it is used for ordinary purposes and the supply is sufficient, the price may be hundreds of gold. However, the actual price also depends on the supply and demand of the market, the amount of production, and the difficulty of transportation, etc. It is difficult to determine its fixed number.
