In search of Technetium
In 1937, A plate of molybdenum metal arrived at Palermo University in Sicily, Italy. From the University of California Berkeley. This discovery was one of the most important disciplines of chemistry in the 37-inch particle accelerating mechanism of the name of an astronomer, Ernst Lawrence's Atom smasher.
The 43rd element was in the empty space of the period table of Dmitry Mendeleev. It is said to be one-manganese due to the manganese's religion. Dmitry Mendeleev created his periodic table according to the mass of the first elemental particle and according to the molecule's behavior with other elements. But to do that, there was a lot of space got left for many unexplained elements. Gradually, according to Mendeleev's prediction, many elements filed those empty spaces without 43rd space.
At that time Emilio Segre, a 32-year-old young scientist working in the Palermo University of Italy. Earlier, working with the prominent scientist Enrico Fermi. With a limited budget, a machine manufactured in the period of time, Fermi's team added new sections to the periodic table of Mendeleev.
Meanwhile, Frederick and Irene Julio Kuri in France showed that radioactive radiation could help transform an element to another element. Madame Curie and Pierre Kurier's son Irene Kurie. She got Noble at chemistry for this discovery in 1935 with husband Frederick Julio Kuri. Segrei thought Lawrence might have created the new element in the particle accelerating device Unknowingly. Lawrence was using 42 atomic numbers, Molybdenum. If the nucleus of a hydrogen atom merges with it, only then the 43rd element can be found. Segre's thought that Lawrence had hit Molybdenum continuously with Hydrogen's Isotope Deuterium. As a result, only a few one-manganese were made in the molybdenum plate. Segre wrote a letter asking for more samples from Lawrence. Lawrence had a little of manganese left, and he sent it happily. With colleague Carlo Perrier, Segre started experimenting on the manganese. The 43rd element was extracted by boiling the sample with Sodium peroxide and hydrogen peroxide. 43 Number single-manganese's half-life was several million years. But the age of the earth is 5 billion years old. So, even if there were some siManganeseanise at the beginning of the earth, almost all of them have now turned into other particles in radioactive erosion. That's why this element is not available naturally. Ten years after the discovery, the name of single-manganese was named Technicianium in 1947. The name comes from the Greek word Technoos. The meaning of Technoos is artificial. Till then Mendeleev's remaining spaces of the periodic table are also completed. Segre later played an important role in the discovery of the element Astatine 85. This invention was the breakthrough and the pioneer of heavy elemental discovery. In 1939, American scientist Edwin McMillan created the 93rd Elemental, Neptunium in the Berkeley Radiation Lab. In February of 1941, Glenn Sieberg made the 94th element. Laboratory With the help of Segre, Seaborg proved that his invention was actually plutonium, which could be used to make a nuclear bomb. Siborg created more than nine elements artificially. In his honor, the 106th element was named Seaborgiumm.
On the way of the discovery of Technetium, the periodic table has reached the 118th Elemental Oganasion. These new elements are useful in any way that nobody imagined. Smoke detector equipment, from spacecraft fuel to terrible weapons. However, the best inventions title was of Technetium and his six-hour half-life Isotopes. Segre and Siborg made this Isotop. 80 percent of the ingredients used in nuclear medicine in the world were Radioactive Isotope technetium.
