WebDec 15, 2024 · Boron belongs to group 13 of the periodic table, and its electronic configuration is 2,3. This means it has three electrons in its valence shell, two in the 2s orbital and one in the 2p orbital. How to Make Lewis Dot Structures? A Lewis dot structure is a graphic representation of the electron distribution around atoms. WebSep 15, 2024 · At first, a valence bond calculation was performed with the bonding situation with two electrons in each boron-2s orbital and one electron in the π x and one electron in the π y orbitals (VB-1, Fig. 1). In total, six structures were used. The energy as a function of the B-B distance is plotted in Fig. 2 (VB-1).
