प्रश्न
How would you explain the fact that the second ionisation potential is always higher than the first ionisation potential?
Advertisements
उत्तर
- Second ionization potential is always higher than the first ionization potential.
- Removal of one electron from the valence orbit of a neutral gaseous atom is easy so first ionization energy is less. But from a uni positive ion, removal of one more electron becomes difficult due to the more forces of attraction between the excess of protons and less number of electrons.
- Due to greater nuclear attraction, second ionization energy is higher than first ionization energy.
