Atomic orbitals are classified according to the number of radial and angular nodes. A radial node for the hydrogen atom is a sphere that occurs where the wavefunction for an atomic orbital is equal to zero, while the angular node is a flat plane. [4] Molecular orbitals are classified according to bonding character. Molecular orbitals with an ...
The angular factors of atomic orbitals Θ(θ) Φ(φ) generate s, p, d, etc. functions as real combinations of spherical harmonics Y ℓm (θ, φ) (where ℓ and m are quantum numbers). There are typically three mathematical forms for the radial functions R ( r ) which can be chosen as a starting point for the calculation of the properties of ...
The + hydrogen-like atomic orbitals with principal quantum number and angular momentum quantum number are often expressed as = (,)in which the () is the radial part of the wave function and (,) is the angular dependent part.
In quantum physics, a wave function (or wavefunction) is a mathematical description of the quantum state of an isolated quantum system. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). Wave functions are complex-valued. For example, a wave function might assign a complex ...
The total angular momentum quantum number j ranges from 1/2 to n−1/2. The orbitals for a given state can be written using two radial functions and two angle functions. The radial functions depend on both the principal quantum number n and an integer k, defined as:
In a simplistic one-electron model described below, the total energy of an electron is a negative inverse quadratic function of the principal quantum number n, leading to degenerate energy levels for each n > 1. [1] In more complex systems—those having forces other than the nucleus–electron Coulomb force—these levels split.

In the case of objects outside the Solar System, the ascending node is the node where the orbiting secondary passes away from the observer, and the descending node is the node where it moves towards the observer. [5], p. 137. The position of the node may be used as one of a set of parameters, called orbital elements, which
