I got quite confused with the math in ThomasFermi's approximation.
I thought it was supposed to approximate a length but the math from a textbook gives energy instead. I don't understand what is it trying to approximate. My professor told me that normal conductors screen electric field at a very short distance ≈1 Angstrom. He said that is the ThomasFermi approximated length. How to derive that length?

However, I agree that I should have been more specific with the questions. Please allow me to go to library again and pull out the book again. Also thank you for trying to help.
