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;
