Questions: Question 7 of 30 Which of the following is true concerning successive ionizations of an atom and its ions? A Each successive ionization requires less energy to achieve. B All ionizations require the same amount of energy. C The amount of energy required to achieve a successive ionization doubles with each electron removed. D Each successive ionization requires increasing amounts of energy.

Solution Steps

Ionization energy is the energy required to remove an electron from an atom or ion. As electrons are removed, the remaining electrons experience a stronger effective nuclear charge, making them more difficult to remove.

For each successive ionization, the electron is being removed from an increasingly positive ion. This means that the remaining electrons are held more tightly by the nucleus, requiring more energy to remove each subsequent electron.

• Option A: Incorrect. Each successive ionization requires more energy, not less.
• Option B: Incorrect. The energy required increases with each ionization.
• Option C: Incorrect. The energy does not necessarily double; it increases, but not in a simple doubling pattern.
• Option D: Correct. Each successive ionization requires increasing amounts of energy.
• Option E: Incorrect. All ionizations are endothermic, requiring energy input.
