WebJan 30, 2024 · A boron atom only has 3 electrons in its outer level, and there is no possibility of it reaching a noble gas structure by simple sharing of electrons. Is this a problem? No. …
WebThis happens in many cases, such as when an amine reacts. In other cases, an atom already bonded may donate electrons, such as in boron trichloride. Finally, borane gas itself can engage in 3-center two electron bonding which is really weird, but provides a full octet when two boron atoms share the bonding electrons in a boron-hydrogen bond.
