ABSTRACT

Boron occurs in two naturally occurring isotopes, B10 and B11. Although the B11 isotope forms the major chunk of the naturally existing isotopes, the existence of the B10 isotope is of considerable significance due to its large cross section for thermal neutron capture. The boron atom has five electrons and its electronic configuration in the ground state can be represented as below. The singlet state can be observed in borylene (:B-H). In terms of electron orbitals, this six-electron molecule has a core shell (1σ), a bonding pair (2σ), and a lone pair of electrons (3σ) on the boron atoms [3, 4]. Boron in most stable compounds exhibits an oxidation state of +3, which is achieved by promoting an electron from the 2s to the 2p orbital.
