Which of the following correctly represents the third ionization of aluminum? A)Al⁺² (g)+ e^- → Al⁺¹ (g) B)Al (g)→ Al⁺ (g)+ e^- C)Al^-2 (g)+ e^- → Al^3- (g) D)Al⁺² (g)+ e^- → Al³⁺ (g) E)Al⁺² (g)→ Al³⁺ (g)+ e^-

Question

Quizplus · Accepted Answer

The third ionization of aluminum would involve the removal of a third electron from an aluminum atom or ion. Option E correctly represents this, showing that the third electron is removed from the aluminum ion in the gas phase, forming a 3+ ion (Al3+) and a free electron. This is represented by the equation Al⁺² (g)→ Al³⁺ (g)+ e^-. Options A, B, and C are incorrect as they do not represent the removal of a third electron from aluminum. Option D incorrectly represents the formation of a 3- ion rather than a 3+ ion.
