Element 114’s electron configuration is [Rn] 5f146d107s27p2. As a result of relativistic effects, element 114 has three outer p orbitals with different symmetries: p1/2 (m=1/2), p3/2 (m=1/2), p3/2 (m=3/2). (In lighter elements the three p orbitals px, py, pzare symmetri...
for instance,darmstadtium, which precedes the island of stability, has a typical half life measured in microseconds, element 114's isotope with atomic mass 289 stays around

Mass Number The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mas...
Flerovium is a superheavy synthetic chemical element; it has symbol Fl and atomic number 114. It is an extremely radioactive synthetic element, named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in...
An artificially produced radioactive element with atomic number 114 that has only been produced in trace amounts and has five observed isotopes with mass numbers ranging from 285 to 289. Its most stable isotope has a half-life of about 2.7 seconds. SeePeriodic Table. ...
However, the names attributed to these products corresponded most times to the real nature of the element. This is the case for fluorine in fluorspar ores (fluorite, CaF2), as for aluminum in alum. Thus, the origin of the word “fluorine” comes from the Greek root “fluo-” (φλυω...
