Where can I find the the orbital energy and the orbital radius?
For example, the ground stata of Li atom, the data of orbital energy and orbital radius for 1s and 2s. Where can it be found?
Thanks
Consult any In-Organic Chemistry book or any Physics Book.Specially in Chemistry book look the Nuclear Bonding or Mendelief's Periodic Table Chapters or Find relevent chapters of Modern Physics in any degree level or high school level book.
Alternatively, check the CRC Handbook of Chemistry and Physics, a standard compendium of a lot (and I mean a *lot*) of different information about physical and chemical properties of individual elements, substances and materials, fundamental constants etc.
It's available online at: http://www.hbcpnetbase.com/
As usual, it has to be said "it depends". What do you need these values for and what do you want to do with them?
If you only need atomic orbital energies and radii or need these values say as a trend indicator, you will find them tabulated in some books like the CRC Handbook as indicated by Dimitri. If you want to know these values in some compounds, like organo-metallic complexes, maybe it would be necessary to do some quantum chemistry calculations.
Yet, the question of an "orbital radius" is also depending on your definition of an orbital etc., so you can run into subtle difficulties if you don't pay attention.
