Explain how the attraction that the nucleus exerts on an electron changes, with the principal energy of the electron.
Principle energy levels are denoted by Principle quantum numbers as n = 1,2,3,4 etc. n=1 means 1st energy level,n=2 means 2nd energy level etc. In hydrogen atom there is one proton and one electron in the first energy level. Electron exerts attraction for the nucleus due to proton. But as more and more electrons are added in various orbitals, the attraction for the nucleus decreases due to ...
The solution explains how attraction affects electron changes.
