Understand that ionization refers to the process of removing electrons from an atom or ion, resulting in a positively charged species.
The first ionization removes one electron from the neutral atom: \(\text{Mn} (g) \rightarrow \text{Mn}^{+} (g) + e^{-}\).
The second ionization removes a second electron from the singly charged ion: \(\text{Mn}^{+} (g) \rightarrow \text{Mn}^{2+} (g) + e^{-}\).
The third ionization removes a third electron from the doubly charged ion: \(\text{Mn}^{2+} (g) \rightarrow \text{Mn}^{3+} (g) + e^{-}\).
Therefore, the third ionization of Mn is represented by the equation \(\text{Mn}^{2+} (g) \rightarrow \text{Mn}^{3+} (g) + e^{-}\), which matches the correct answer.
