Technetium

 43) Technetium

Technetium An element found right below uranium in the periodic table that does not occur naturally in the earth. Rather, it is created artificially in particle accelerators and nuclear reactors. At the beginning of the twentieth century, most of the periodic table 

Although the elements had been discovered, only a few boxes were empty, which means that the atomic number of the elements found in those boxes had not yet been discovered. And one of those elements was technetium.

How many times has this happened, a discovery was claimed which proved to be false, because today we know that technetium does not occur naturally. Finally, ten years later, in 1935, it was created in a particle accelerator. Technetium is the first such element. 

Which was created by artificial method.

Technetium is a radioactive element which means it emits dangerous radiation (gamma rays) all the time. This is why its use is very limited.

🌟Discovery

It was in the 1920s when a research team of scientists was busy looking for elements with atomic numbers 43 and 75, which were not discovered at that time. However, it was known that there are empty spaces in the periodic table with atomic numbers. 

43 and 75. After a period of five years, the team of scientists announced that they had   Elements with atomic number 43 and 75 have been discovered. They named the element with atomic number 43 as masurium, while the element with atomic number 75 was named rhenium. This was because masurium was discovered in Masurenland, East Germany. 

Similarly, rhenium was discovered in the Rhineland region of West Germany. However, it was later found that his claim regarding the discovery of these elements was false.

Chemists continued to search for the element with atomic number 43. Finally, in an experiment at the University of California particle accelerator, it was found as a by-product. A particle accelerator is a machine that contains subatomic particles such as 

Protons are accelerated (accelerator means to continuously increase the speed of something). When protons collide with atoms of different elements like gold, copper and tin etc. at a very high speed (close to the speed of light). 

If there is, this proton gets stuck in it. Because of which, due to the increase in its atomic number, it changes into a new element. For example, there are seven protons in an atom of nitrogen, while there are seven protons in an atom of oxygen. 

Eight protons. Which means that if there are seven protons in an atom, then that atom is nitrogen.
