William Lipscomb studied its compounds extensively and the banana bond appears in its simple hydride.
The diamond-square-diamond or DSD mechanism explains the structural rearrangements in some compounds with this element and the three-center two-electron-bond is seen in many of compounds containing it. William Lipscomb studied its compounds extensively and the banana bond appears in its simple hydride. Its halides are typical Lobe-LUMO Lewis acids and when added to water produces its simplest oxoacid. Injections of it are used with a neutron beam as a form of radiotherapy and its simplest oxoacid acid is used as a coolant in (*) nuclear reactors. It is a common p-type dopant for semiconductors as it has one less valence electron than the major component of the semiconductors, silicon. The decay of beryllium-10 results in an isotope of this metalloid with weight 10. For 10 points, name this element with chemical symbol B.
