Which of the following correctly represents the third ionization of aluminum?
a) al^2+ (g) + e^- > al^+ (g)
b) al^2+ (g) > al^3+(g) + e^-
c) al^2- (g) + e^- > a1^3- (g)
d) al (g) > al^+ (g) + e^-
e) al^2+ (g) + e^- > al^3+ (g)

Option B

Explanation:

Energy required to remove outermost electron from an neutral atom is called ionization energy or first ionization energy ()

Energy required to remove an electron from M+ ion is called second ionization energy ().

Energy required to remove an electron from M2+ ion is called third ionization energy ).

Therefore, among the given options:

Therefore, the correct option is b
