# Which equation represents the second ionization energy of magnesium?

Mg(g) → Mg2+(g) + 2e−

The second ionization energy of magnesium can be represented by the equation Mg(g) → Mg2+(g) + 2e−. This equation shows that the second ionization energy of magnesium is the energy required to remove two electrons from a magnesium atom in the gaseous state. The second ionization energy of magnesium is greater than the first ionization energy of magnesium because it takes more energy to remove two electrons from an atom than it does to remove just one electron.
