When someone hears about expensive materials he would probably think of gold, diamond, or maybe some exotic medical components, but the truth is far from that.
The fact is that the most expensive material in the world right now, is something called the “element 118” or “Oganesson”.
Element 188 or “Oganesson”, is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal.
The element, No. 118 on the Periodic Table of Elements, had previously been designated ununoctium, a placeholder name that means one-one-eight in Latin.
The material was first discovered by scientists at the Joint Institute for Nuclear Research in Dubna, Russia and the Lawrence Livermore National Laboratory (LLNL), California first made element 118, oganesson, in 2002.
The Island of Stability is a term from nuclear physics that describes the possibility of elements, which have particularly stable “magic numbers” of protons and neutrons.
