Four new elements in the Periodic Table
Thanks to the discoveries of Russian, American and Japanese scientists, theóin the siódmy period on the Periodic Table is now complete. The International Union of Pure and Applied Chemistry has officially added elements with atomic numbers 113, 115, 117 and 118 to the Periodic Table.
The new elements have been given temporary names: Ununtrium, Ununpentium, Ununseptium and Ununoctium. The new elements belong to the transuranic groupóThe elements were obtained in laboratory conditions, which means that they do not occur naturally in nature.
Theoretically, there are even heavier elements in the periodic table óstego. However, so far they have not been obtained. Scientists argue over where the boundary of the Periodic Table lies. Próto create new elementsóThe particles are unsuccessful, as they immediately disintegrate. In the future, however, it is possible that we will find new items to add to the Periodic Table of Elements.
