Explain Schrodinger wave equation and also explain `sigma ` and `sigma ^(2)` one electron system.

Explanation

When Schrodinger equation is solved for hydrogen atom.
(i) The solution gives the possible energy levels corresponding wave function ( s) of the eletron associated with each energy level.
(ii) These quantized energy states and corresponding wave function which are number hydrogen depend only upon.
(iii) When an electron is in any energy state the wave function corresponding to that energy state contains all information about the electron.
the quantum mechanical results of the the hydrogen atom spectrum including some phenomena that could not be explained by the bohr model.
for one electron species the energy of orbitals based upon principle quantum number n
