What are the elements of rare lands? Science answers!

The elements of rare lands are extremely important for the world as we know today.mainly because they activate the functioning of various technological equipment. They are used to make computers, TV screens, smartphones as well as other civil and military devices.

Although it is called “rare, and although they have exotic names such as Itérbio, these elements are more abundant than others that we easily find on Earth. But why are they rare?

The reason for this is that they concentrate abundant in several ore deposits that are not widely exploited.. Therefore, only a few parts of the world can meet global demand for rare soil elements.

Britannica Enciklopedi, “Rare land ore deposits are located in various parts of the world. Main beds are located in China, USA, Australia and Russia, while there are other live beds in Canada, India, South Africa and Southeast Asia,” he explains.

For example, Toyota uses more than 8,500 tons of rare land elements per year in Prius model hybrid car production.

In addition to the use of products designed for the population, these elements are also essential in the production of military equipment such as radars, satellites, aircraft, missile routing systems.

According to the Britannica encyclopedia, the elements of rare lands are so much available in daily life that they are often not noticed. However, almost all technological equipment are produced with these “components”. Even a simple lighter you find in any corner contains one of these elements on your stone (bouquet).

What are the elements of rare lands?

The elements of rare lands have not been created by man – they have existed on earth since their formation. But, The discovery took place in 1787 when the Swedish mineralologist and chemist Carl Axel found a mixture of various elements of rare lands of Arrhenius.

Despite the discovery, scientists could not be isolated one separately until 1803: Cerius.

In total, 17 The element of rare land was discovered, they are all available periodic picture. These metals belong to the 15 Lantanid group. The other two are metallic and have similar properties, although not part of this group.

These are called Lantanid, because they are classified immediately after the Lantnium in the periodic table. These are metals with magnetic and optical properties and have very similar chemical properties.

Although not very rare on earth, it is difficult to find alone because they are usually mixed with other minerals.

Get to know the 17 elements of rare lands:

1. LANTANIO (LA)
2. Care (CE)
3. Praseodimum (PR)
4. Neodimum (nd)
5. Promécio (PM) – Radioactive and rare
6. Samary (SM)
7. Europio (I)
8. Gadolinium (GD)
9. Terbian (TB)
10. Dysprosium (DY)
11. Holmio (Ho)
12. Erbio (ER)
13. Túlio (TM)
14. Iérbio (YB)
15. Lutécio (lu)
16. Scandio (SC)
17. ITRIO (Y)

Experts argue that neodimum, terbium, discipós and prasodyum are among the most widely used rare land elements in the production of various materials. They are widely used In addition to other technological products, battery production for automobiles, smartphones, medical equipment, LED screens.

Are the elements of rare lands rare?

Most of the rare lands are removed in China, but these minerals also have deposits in the United States and Brazil. .In addition, countries such as South Africa, Thailand, India and Australia mining these elements.

Even when they are relatively abundant on earth, some scientists question whether the term “rare” is really suitable for defining them.

In an interview with the site LifeguardPaul Ziemkiewicz, Director of Western Virginia Water Research Institute (USA), argued that “elements of problematic lands” would be a more appropriate term to describe these minerals.

The biggest challenge with the 17 elements of rare soil, They are usually mixed with other compounds and substancesThis makes your insulation quite complex.

“The problem is that they are not so concentrated in one place. There are about 300 milligrams per kilogram. [0,005 onças por libra] Rare lands in the United States of the United States. If you make a hole in your backyard, you’ll get more or less, Ziem Ziemkiewicz said.

In short, these elements are not exactly rare, but their extraction is much more complex than other mineral species. Fortunately, some regions concentrate these metals in more amounts, which makes mining more suitable in these places.

Nevertheless, even in these areas, it is necessary to distinguish between various impurities to obtain an element of rare soils in pure forms. For this reason, many scientists are examining ways to make the extraction process of these materials more efficient. Some even seek ways to recycle them from electronic and old devices.

Despite the abundance in space, some elements are almost here; The composition of the planet helps to explain why it is so common in the universe. Do you want to know more? Understand why the abundant elements in the universe are so rare on earth. Until next time!
