Which of the following represents the third ionization of Mn?
A
Mn− (g) + e− → 2 Mn2− (g)
B
Mn2+ (g) → Mn3+ (g) + e−
C
Mn2− (g) + e− → 2 Mn3− (g)
D
Mn (g) → Mn3+ (g) + 3 e−

Understand the concept of ionization energy: Ionization energy is the energy required to remove an electron from an atom or ion in the gaseous state.
Identify the process of ionization: The third ionization energy refers to the energy required to remove the third electron after the first two have already been removed.
Analyze the given options: The correct representation of the third ionization of Mn should involve the removal of the third electron from Mn2+ to form Mn3+.
Evaluate the chemical equations: The correct equation for the third ionization of Mn is Mn2+ (g) → Mn3+ (g) + e−, as it shows the removal of one electron from Mn2+.
Compare with the image: The image shows the equation Mn (g) → Mn3+ (g) + 3 e−, which represents the overall removal of three electrons, not specifically the third ionization step.
