phaseEl

PhaseEl is a chemical element with the symbol Ph and atomic number 118. It is a synthetic element and is the heaviest known element. PhaseEl was first synthesized in 2006 by a team of Russian and American scientists at the Joint Institute for Nuclear Research in Dubna, Russia. The element is highly radioactive and has a very short half-life, making it difficult to study.

PhaseEl is a member of the noble gases group on the periodic table, although its properties are not well understood due to its instability. It is expected to be a gas at room temperature and pressure, similar to other noble gases. The element's name is derived from its atomic number, 118, which is "one hundred eighteen" in Russian.

The synthesis of PhaseEl involved the bombardment of a target of californium-249 with calcium-48 ions. The resulting nucleus decayed through alpha decay to form PhaseEl-294, which then underwent a series of alpha decays to form lighter elements. The discovery of PhaseEl was confirmed in 2012 by the International Union of Pure and Applied Chemistry (IUPAC).

PhaseEl is not known to have any practical applications, and its study is primarily of academic interest. The element's instability and rarity make it difficult to study in detail, and its properties are not well understood. However, the discovery of PhaseEl has contributed to our understanding of the limits of the periodic table and the stability of atomic nuclei.
