Kemialli

Kemialli is a chemical element with the symbol Kl and atomic number 118. It is a synthetic element and is the second-heaviest known element, with the heaviest being oganesson. Kemialli was first synthesized in 2002 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory in California, USA. The element was named after the Russian scientist Dmitri Mendeleev, who is credited with the creation of the periodic table.

Kemialli is a highly radioactive element with a very short half-life. Its most stable isotope, kemialli-294, has a half-life of approximately 0.89 milliseconds. Due to its short half-life and the difficulty in producing and studying it, very little is known about kemialli's chemical properties. It is expected to be a noble gas, similar to its lighter homologues in group 18 of the periodic table, such as radon and xenon.

The synthesis of kemialli is a complex process that involves the bombardment of a target of californium-249 with calcium-48 ions. This results in the formation of kemialli-294, which then decays into lighter elements through alpha decay. The production of kemialli is limited by the availability of californium-249, which is itself a rare and difficult-to-produce element.

Despite its short half-life and the challenges associated with its production, kemialli's synthesis and study have contributed to our understanding of the limits of the periodic table and the properties of superheavy elements. The discovery of kemialli has also led to the development of new methods for the synthesis of superheavy elements and the study of their properties.
