Some compounds of boron. Some of the other important compounds of boron are borax, orthoboric acid and boron hydrides. Let us know something about these compounds. Borax: Borax is an important boron compound. It has a white crystalline solid structure with formula of Na 2 B 4 O 7. 10H 2 O.Boron - Compounds | Britannica,Boron - Boron - Compounds: In its compounds boron shows an oxidation state of +3. The first three ionization energies of boron, however, are much too high to allow formation of compounds containing the B3+ ion; thus, in all its compounds boron is covalently bonded. That is, one of boron’s 2s electrons is promoted to a 2p orbital, giving the outer electron configuration 2s12p2; the s and p,Boron Compounds - an overview | ScienceDirect Topics,(a) Boron compounds. Boron compounds have been used since the 1950s in Australasia and Europe for protecting timber, but borate standards have only been issued by AWPA for above ground, protected uses. A detailed look at the worldwide status of boron compounds as wood preservatives can be found in Hamel (1990) and Amburgey et al. (1997).
