Electron orbitals and Hund's rule
by RS  admin@creationpie.com : 1024 x 640


1. Electron orbitals and Hund's rule
Note: The code for these orbitals was changed from ASP to PHP and not yet fully checked.

2. Electron orbitals and Hund's rule
Hund's rules provide a way to determine the electron configurations of an atom and is related to the idea of valence.

It is interesting that, though taught in chemistry class as a precise rule, the rule fails to predict some actual electron levels in practice.

This was originally discovered by writing a program to generate the s, p, d and f levels for the atoms. When checked with chemistry books (on atoms), it appeared that the program did not work for some levels. After some investigation, it was discovered that the program was correct but that the rule did not apply to some atoms.

3. Electron orbitals
Here are the electron orbital levels for the atomic elements.

These electron orbital levels use the aufbau principle. Some elements in the f levels do not appear to use this principle.

4. Orbitals
In each orbital representation in the table, the exponent indicates how many electrons are present in each sublevel. Each sublevel can hold a specified maximum of electrons.
