Boron (5 B) naturally occurs as isotopes 10 B and 11 B, the latter of which makes up about 80% of natural boron. There are 13 radioisotopes that have been discovered, with mass numbers from 7 to 21, all with short half-lives, the longest being that of 8 B, with a half-life of only 771.9(9) ms and 12 B with a half-life of 20.20(2) ms.
BODIPY is the technical common name of a chemical compound with formula C 9 H 7 BN 2 F 2, whose molecule consists of a boron difluoride group BF 2 joined to a dipyrromethene group C 9 H 7 N 2; specifically, the compound 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene in the IUPAC nomenclature. [1] The common name is an abbreviation for "boron ...
The matter was handed to the Danish branch of IUPAC which, despite this, voted in favour of the name bohrium, and thus the name bohrium for element 107 was recognized internationally in 1997; [58] the names of the respective oxyanions of boron and bohrium remain unchanged despite their homophony.
