Boron - Wikipedia
Atomic structure. Boron is the lightest element having an electron in a p-orbital in its ground state. Unlike most other p-elements, it rarely obeys the octet rule and usually places only six electrons [49] (in three molecular orbitals) onto its valence shell.

23.4: Boron and Its Amazing Structures - Chemistry LibreTexts
2020年8月14日 · Instead of forming a metallic lattice with delocalized valence electrons, boron forms unique aggregates that contain multicenter bonds, including metal borides, in which boron is bonded to other boron atoms to form three-dimensional networks or clusters with regular geometric structures.
Boron | B (Element) - PubChem
Molecules, atoms, and ions of the stable isotopes of boron possess slightly different physical and chemical properties, and they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights.
