The discussion revolves around the applicability of the Rydberg equation to atomic models, particularly its relevance to hydrogen and hydrogen-like systems, as well as the purpose and limitations of molecular orbitals in describing many-electron systems.
Participants express differing views on the applicability of the Rydberg equation and the complexity of molecular orbitals, indicating that multiple competing perspectives remain without a clear consensus.
The discussion highlights limitations in the applicability of the Rydberg equation and the challenges in teaching molecular orbital theory, but does not resolve these issues or provide definitive answers.
This discussion may be of interest to students and educators in chemistry and physics, particularly those exploring atomic and molecular theory.
In principle it should only be applied to hydrogen-like systems--systems with one electron in a Coulomb potential. Anything beyond a one-electron (or effectively one-electron) systems is not exactly solvable, and a Rydberg-type equation involving one-electron energy differences is, in principle, wrong.f24u7 said:Hi, I have a little question about atomic models
1. Does Rydberg equation only apply to hydrogen
The purpose is to give a simple one-electron type of theory to a more complication many-electron system (a molecule). The limitation are legion, but interestingly molecular orbitals are still useful. A reference that I like regarding orbital theories is a book called "The Physics of the Chemical Bond". The author escapes me at the moment.2. What is the purpose and limitations of molecular obitals
hmm... I'm not sure. But, probably it is too advanced for a high school text. Regardless, here is a link to the book on amazon:f24u7 said:I was wondering if the book is suitable for high school level?
you're welcome.Thanks for the answer. the explanation is very clear
