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.

Chemistry of Boron (Z=5) - Chemistry LibreTexts
Jun 30, 2023 · Boron is the fifth element of the periodic table (Z=5), located in Group 13. It is classified as a metalloid due it its properties that reflect a combination of both metals and nonmetals.
Boron | History, Uses, Facts, Physical & Chemical Characteristics
Chemical Characteristics. Amorphous form of boron is reactive. In crystalline form, boron is quite unreactive. It makes stable covalent bonds with other compounds and does not forms ionic bonds. Boron combines with air to form boron trioxide, which acts a protective layer on the surface of boron and protects the metal from further oxidation.
