9.7: Molecular Orbitals - Chemistry LibreTexts
In the molecular orbital approach, the overlapping atomic orbitals are described by mathematical equations called wave functions. The 1 s atomic orbitals on the two hydrogen atoms interact to form two new molecular orbitals, one produced by taking the sum of the two H 1 s wave functions, and the other produced by taking their difference:

These directional differences lead to the formation of two different classes of molecular orbitals. The above figure shows how two px atomic orbitals interact.

Like an atomic orbital, each molecular orbital can accommodate two electrons. Thus the lowest energy arrangement for H 2 would place both electrons in the a 1s MO with paired spins. This molecular electron configuration is written (σ 1s) 2, and it corresponds to a covalent electron-pair bond holding the two H atoms together.
The Orbitron: 2p atomic orbitals wave function equations
Table of equations for the 2p orbital. The radial equation for the 2 px, 2 py, and 2 pz orbitals is the same in each case. The angular functions are the same but substitute y and z as appropriate in the formula for Y2px given above. Substitute similarly for the wave equations ψ2py and ψ2pz.

The Orbitron: 2p atomic orbital wave function - University of …
Each 2 p orbital has a planar node normal to the axis of the orbital (so the 2 px orbital has a yz nodal plane, for instance) but no spherical nodal surfaces. The higher p -orbitals ( 3 p, 4 p, 5 p, 6 p, and 7 p) are more complex since they have one or more spherical nodes as well.
The Orbitron: 2p atomic orbitals
For any atom, there are three 2 p orbitals. These orbitals have the same shape but are aligned differently in space. The three 2 p orbitals normally used are labelled 2 px, 2 py, and 2 pz since the functions are "aligned" along the x, y, and z axes respectively.
Why is there a difference between O2 and B2 sigma 2p molecular …
2013年10月24日 · The molecular orbital diagram for $\ce{O2}$ says that the sigma 2p bonding molecular orbital is lower in energy than the pi 2p bonding molecular orbital. Why is this not the case in the $\ce{B2}$ MO diagram?
