Figure 1. The 2p sublevel, for the elements boron (Z = 5), carbon (Z = 6), nitrogen (Z = 7), and oxygen (Z = 8). According to Hund’s rule, as electrons are added to a set of orbitals of equal energy, one electron enters each orbital before any orbital receives a second electron.
of each electron in a particular orbital. By now you should be familiar with the “s, p, d, f” notation of orbitals. Each of these orbitals represents the probability of there being an electron in that location. For “s” orbitals, there can be no more than two (2) electrons in the orbital. The s orbital has a spherical shape.
The process in which we are now about to engage is very similar to that which we used in class for generating the molecular orbital energy level diagram for the BH three molecule. In that case we had a central boron and three hydrogens around it, and we made some hydrogen linear combinations.

The order of orbital filling is therefore 4s, 3 d, 4 p, 5 s. The diagram opposite gives the order of orbital filling in many-electron atoms based on the (n + l) rule. Start at the 1s orbital and follow the direction of arrows from right to left. Orbitals with the same value of (n + l) are arranged along diagonals.
diagram below. Another molecule which exhibits resonance is SO 3. You should be able to fi ll in the missing diagrams. And then you write the Lewis/line resonance diagrams as: Now try to form the Lewis diagram for benzene, C 6 H 6, where the carbon atoms form a ring. Expect reso-nance. Now we write the fi nal Lewis resonance diagram as: and the ...
The diagram for BH3F- ion is really a superposition of the two diagrams before, except that the HOMO and LUMO have formed a new bonding and antibonding orbital for the new B-F bond. Figure AB4b.6. Molecular orbital interaction diagram for formation of an adduct between a fluoride ion and borane.
Boron carbide (B 4 C) Boron nitride (BN) Boron tribromide (BBr 3) Boron trichloride (BCl 3) Boron trifluoride (BF 3) Boron trioxide (B 2 O 3) Interesting facts: It does not occur freely in nature in its elemental form. It is found in borax, boric acid, colemanite, kernite, ulexite and borates. It is sometimes found in volcanic spring waters.
b) Select an orientation for the p orbitals on boron. c) What interaction are possible between the set of hydrogens and the boron 2s orbital? d) What interactions are possible between the set of hydrogens and one boron 2p orbital? e) What interactions are possible between the set of hydrogens and the second boron 2p orbital?
