Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
Explanation:
Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
There is an approximate amount of energy which is needed to overcome the attractive force between the electrons and nucleus.
If you put less than the required ionization energy, then the electrons can not be removed.
