However, the hobby of collecting elements is unrealistic for ordinary people. In fact, more people are most concerned about the price of this topic.
How much does it cost to complete all the elements? In fact, it is hard to imagine how much it would cost to collect all these elements. Even Bill Gates, once the richest man in the world, can't afford all the elements, and there are many valuable and worthless elements in the periodic table, which can't be bought with money.
At the same time, there are some radioactive elements that cannot be stored because of their instability, even if the harm to human body is not considered. Take Bill Gates as an example. The element wall presented by Bill Gates at home, in which element 75-rhenium is relatively expensive, belongs to one of the newly discovered elements, and the price is1kg240,000 to1180,000 RMB.
There are 1 18 elements in the periodic table at present. From 1 elemental hydrogen to element californium 98 can be found in nature, but the last 20 elements are all synthetic and do not exist in nature.
A collection of elements. First of all, the common gas elements in our life, such as oxygen, nitrogen and hydrogen, are widely distributed in nature, so it is not very difficult to extract them, so the price of 1g is not very high.
Secondly, common metal elements, such as gold, silver, copper, iron and so on, can be found everywhere, easy to collect and low in price. But the emphasis is on some rare metal elements behind the periodic table.
Madame Curie, a world-famous chemist, I believe many people have heard that she won the Nobel Prize for discovering two new elements-polonium and radium.
Although Madame Curie discovered radium, she could not afford a gram of radium in her future research. In the 1920s, the price of one gram of radium was as high as $654.38 million, from which we can see the value of these rare elements.
It is reported that the current market price of radium has already exceeded $ 654.38+ 10,000 a gram, but radium is still not the most expensive element.
The most expensive element in the world-francium At present, the most expensive natural element is francium (fāng), the chemical symbol is Fr and the atomic number is 87. It is radioactive and belongs to alkali metal elements. It is very unstable, with a half-life of only 22 minutes, so it is very rare in nature.
In the scientific community, no one has ever seen francium with a weight as high as1g. At present, only a few francium atoms are produced in the laboratory. If you want to buy it, the production cost of francium with a weight of 100g can reach billions of dollars by simple estimation!
Uranium, the most expensive synthetic element, is the most expensive among synthetic elements. Transuranic elements refer to elements with atomic number greater than 92 (uranium elements), most of which are discovered and prepared by artificial nuclear reactions, and only a few transuranic elements exist in nature.
At present, californium (kāi) is the most expensive transuranic element. Because of its great role in the field of nuclear medicine, according to the time, manpower and material costs of the accelerator, its market price has already reached 65,438 438+ 10/00000 USD 65,438+0g.
But in real life, the most expensive natural element you can really buy through relevant channels is lutetium (L incarnation), which is the most stable metal element after rare earth, and the market price is about 20g 10000 USD.
Conclusion. The uses of chemical elements are quite extensive, and if you want to collect all the elements in the periodic table, the price is not important, but the value of chemical elements depends not only on its scarcity, but also on its quality, such as purity, processing, shape and so on.
The most important point is that the elements at the back of the chemical periodic table are more radioactive, not easy to touch, harmful and even threatening the world.
So some elements will not be sold, only for researchers to study. Generally speaking, it is "difficult to go to the sky" to collect all the elements.
