fooliumile
Fooliumile is a hypothetical element with the proposed chemical symbol Fl and atomic number 121. As a transuranic element, it is expected to be highly unstable and radioactive, existing only for extremely short periods of time before decaying into lighter elements. Its theoretical electron configuration suggests it would be the first element in the g-block of the periodic table, a region not yet populated by known elements.
The existence and properties of fooliumile have not been experimentally confirmed. Its study is primarily within
The synthesis of element 121 would likely involve colliding heavy atomic nuclei at extremely high energies
