n. Symbol Bh
An artificially produced radioactive element with atomic number 107 for which isotopes have been observed with mass numbers ranging from 260 to 275, all of which decay by alpha-particle emission. The isotope with mass number 264 has the longest confirmed half-life (1.3 seconds), although longer half-lifes have been reported for some of its heavier isotopes. See Periodic Table.
