how the states or energy levels of electrons can be understood in a easy physical way?

Question

i need explanation from kronieg penny model

Answer 1

Kronieg Penny model is easy only when compared to the Schroedinger general solution. Take a look at

or other Internet sites.

To understand the stability of electrons in their orbits a good idea is to apply the De Broglie model: electrons are waves of frequency given by energy = h x frequency (h is the Planck constant). The only stable orbits are those where the number of wave lenghts of the electron are a whole number, in order to fit completely in them. Historically it was the first explanation for the stable orbits of Bohr hidrogen atom.
