Fl is the chemical symbol for the element Flerovium, which is a synthetic element with the atomic number 114. It was first synthesized in 1998 by a team of Russian and American scientists at the Joint Institute for Nuclear Research in Dubna, Russia. Flerovium is classified as a post-transition metal and is part of the group 14 elements in the periodic table. Due to its instability, Fl has no significant commercial applications and is primarily of interest for scientific research. It is produced in minute quantities through nuclear reactions, and its most stable isotope, Fl-289, has a half-life of about 2.6 seconds, making it challenging to study its properties.
