[单选题]
Which of the following ionization energies is the largest in magnitude?
A. The first ionization energy of sodium
B. The second ionization energy of magnesium
C. The third ionization energy of aluminium
D. The fourth ionization energy of silicon
参考答案: D
本题详细解析:
Successive ionization energies are larger, as electrons are removed, there is less electron-electron repulsion, so the remaining electrons are pulled closer to the nucleus, and more energy is required to remove them.
