Orbitals quantum numbers

Much of quantum chemistry attempts to make more quantitative these aspects of chemists view of the periodic table and of atomic valence and structure. By starting from first principles and treating atomic and molecular states as solutions of a so-called Schrodinger equation, quantum chemistry seeks to determine what underlies the empirical quantum numbers, orbitals, the aufbau principle and the concept of valence used by spectroscopists and chemists, in some cases, even prior to the advent of quantum mechanics. 

Quantum Number (Orbital). A quantum number characterizing the orbital angular momentum of an electron in an atom or of a nucleon in the shell-model description of the atomic nucleus. The symbol for the orbital quantum number is l.

Orbitals ju) are characterised by their quantum numbers Orbitals in the positive-energy continuum are characterised by momentum Pfi instead of the principal quantum number In each case we characterise them by the integer p. In the present context no confusion is caused by using a discrete notation for the continuum. 

These methods lead in general to very good agreement between calculated and observed quantities. Rydberg states are also described well. They are characterized by high quantum number orbitals, which are much more extended than valence orbitals. Molecular Rydberg orbitals resemble atomic orbitals since an electron in such an orbital is so far from the nuclei of the...

Rydberg series A Rydberg state is a state of an atom or molecule in which one of the electrons has been excited to a high principal quantum number orbital. A Rydberg series is the set of bound states of the excited electron for a given set of excited electron angular momentum quantum numbers and ion core state.

In this chapter, we will discuss the electronic arrangement of atoms. We will also talk about quantum numbers, orbitals, various rules pertaining to electron-filling, and electronic configuration. 

Energy increases with increasing n + i, where n = the principal quantum number, and = the azimuthal quantum number (orbital angular momentum quantum number).

Atomic orbitals (mathematically described by wave functions) are defined by four quantum numbers, n, /, mi, and i. Electrons may have only certain energies determined by these quantum numbers. Orbitals have different, well-defined shapes s orbitals are spherically symmetric, orbitals are roughly dumbbell shaped, d and/"orbitals are more comphcated. An orbital may contain a maximum of two electrons.
