Question

Explain why successive ionization energies of an element increases

Answer 1

The amount of the Energy required to remove the electron from the Neutral Isolated Gaseous Atom is called as the Ionization energy.

Now, If one electron is removed then if the another electron of the electron is also need to be removed then the amount of the Energy required will be more this is because, when one electron is removed than the no. of the electrons becomes less than the number of the protons in an atom.

As a result the Nuclear Charge of the atom increases and the electrons are attracted towards the center or towards the nucleus. The attraction force thus increases.

Now, the energy will obviously will be more since force has been increased.

Hence, the successive ionization energy is more than the First or the Second Ionization Energy.

Hope it helps.
