What is the energy needed to change an He⁺ ion into an He⁺⁺ ion? (The ionization energy of hydrogen is 13.6 eV). A)13.6 eV B)54.4 eV C)92.9 eV D)112.4 eV

Question

Quizplus · Accepted Answer

The He⁺ ion is similar to a hydrogen atom but with a nuclear charge of +2. The ionization energy is proportional to the square of the nuclear charge (Z²). For He⁺, Z = 2, so the ionization energy is 13.6 eV * 2² = 54.4 eV.
