WebDec 14, 2024 · Instead, ionic boron structures are formed from clusters where the ionic bonding is driven by the molecular orbital structures in these clusters, not by electronegativity (cf. This answer ). Such clusters are internally held together by covalent bonds between the boron atoms, so in this sense boron is still forming covalent bonds. WebJun 12, 2024 · The size of B X 3 + ions, is very small and the ion has high charge density. Thus, following Fajan's rule, boron forms covalent compounds. The sum of the first three ionisation enthalpies of boron is too high, thereby restricting the formation of B X 3 + ions. Thus, boron is forced to form covalent bonds with other compounds. cornerstone medical group oakland md
