Explanation:
Ionization Energy:
Ionization energy is the energy required to remove an electron from an atom. The lower the ionization energy, the easier it is to remove an electron.
Electron Affinity:
Electron affinity is the energy released when an electron is added to an atom. The lower the electron affinity, the less likely an atom is to gain an electron.
Formation of Mg2+, O2-:
- In the case of Mg2+, the ionization energy of Mg is relatively low, making it easier for magnesium to lose two electrons and form the Mg2+ ion.
- In the case of O2-, the electron affinity of oxygen is relatively low, meaning it is less likely for oxygen to gain two electrons and form the O2- ion.
Therefore, Mg2+ and O2- are formed because of the low ionization energy of Mg, allowing it to lose electrons easily, while the low electron affinity of O prevents it from gaining electrons easily.
