Question

Mg+2 ,Mg+and Mg which have heigher ionisation energy and why???​

Answer 1

Answer:

The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.

Answer 2

The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom.

The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.
