manganatomen

Manganatomen is a proposed hypothetical element with the symbol Mn and atomic number 118. It would be a superheavy element, likely a member of the noble gas group (Group 18) if its properties align with theoretical predictions based on its position in the periodic table. As a superheavy element, manganatomen would be highly unstable, with a very short half-life, decaying rapidly into lighter elements. Its synthesis would likely occur in particle accelerators through the fusion of lighter nuclei. Due to its predicted extreme instability and short existence, direct observation and study of manganatomen are currently beyond experimental capabilities. Theoretical models suggest it might exhibit some properties deviating from the trend of lighter noble gases due to relativistic effects, which become significant for very heavy elements. The name "manganatomen" is derived from the Greek word "manganon," referring to manganese, and "atom," indicating its elemental nature. Its existence remains theoretical, and experimental confirmation is yet to be achieved.
