21. Expanding the above equation into atomic orbitals yields 22. Particularly great increases occur after any given block of atomic orbitals is exhausted of electrons. 23. :What if extremely strong magnetic fields are used to deform the core atomic orbitals ? 24. For every element and core ( atomic orbital ) there will be a different binding energy. 25. Molecular orbitals are further divided according to the types of atomic orbitals they are formed from. 26. The radial parts of these atomic orbitals are sometimes numerical tables or are sometimes Slater orbitals. 27. Each atomic orbital is associated with an angular momentum "'L " '. 28. The stationary states ( quantum states ) of the hydrogen-like atoms are its atomic orbitals . 29. The coefficients are the weights of the contributions of the n atomic orbitals to the molecular orbital. 30. The required atomic orbital energies can come from calculations or directly from experiment via Koopmans'theorem.
