Question

arrange the ionisation energy of Mg+,Mg2+,Mg3+. for 11th chemistry ​

Answer 1

Answer:

The third step will have the highest ionization energy. I.E3 > I.E2 > I.E1 Because from a neutral gaseous atom, the electron removal is easy and less amount of energy is required. But from a di positive cation, there will be more number of protons than the electrons and there is more forces of attraction between the nucleus and electron. So the removal of electron in a di positive cation, becomes highly difficult and more energy is required.Read more on Sarthaks.com - https://www.sarthaks.com/919800/magnesium-loses-electrons-successively-form-ions-which-step-will-have-highest-ionization?show=919805#a919805
