eltnt

Eltnt is a chemical element with the symbol El and atomic number 119. It is a synthetic element and is part of the 7th period of the periodic table. Eltnt was first synthesized in 2019 by a team of Russian and American scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and the Lawrence Livermore National Laboratory in California, USA. The discovery was confirmed by the International Union of Pure and Applied Chemistry (IUPAC) in 2020.

Eltnt is a highly radioactive element with a very short half-life. Its most stable isotope, Eltnt-294, has a half-life of approximately 0.69 milliseconds. Due to its short half-life and the difficulty in producing and studying it, very little is known about its chemical properties. It is expected to be a transition metal and is likely to have similar chemical properties to its lighter homologues, iridium and platinum.

The synthesis of Eltnt involved the bombardment of a target of berkelium-249 with calcium-48 ions. This reaction produced a single atom of Eltnt-294, which was then detected by its spontaneous fission. The discovery of Eltnt marks the completion of the seventh period of the periodic table, making it the heaviest element known to science.
