Atomic orbital energy matching is a valid criterion of bond strength only for half filled molecular orbitals. Doubly occupied molecular orbitals built from atomic orbitals differing in energies may be strongly bonding due to high ionic bond-orders....
The electrons orbit the nucleus in electron orbitals that have definite energy levels. The chemical elements can combine to form compounds in fixed ratios to each other, often by sharing the outer orbital electrons. These bonds form by combination of their atomic orbitals or by the formation of ...
(This so-called degeneracy, the possession of the same energy by different wave functions, is also associated with the coincidental numerical agreement of Bohr’s model with experiment.) As soon as a second electron is present, however, the degeneracy is lost. atomic orbitalFigure 2: The ...
The shape of the orbital depends on many factors. The most important are the quantum numbers associated with the particular energy state. These aren, the principal quantum number,l, the orbital quantum number, andm, the angular momentum quantum number. The following table shows some of these sh...
