C) Ge
D) Si

Question

Quizplus · Accepted Answer

Silicon (Si) has the highest first ionization energy among the options given. This is because it is located furthest to the right and top in the periodic table among the choices, which generally indicates higher ionization energies due to increased nuclear charge and decreased atomic radius, leading to a stronger attraction between the nucleus and the valence electrons.
