Beryllium and aluminum have similar properties because
A) both have similar electron affinities.
B) both have almost identical ionization energies.
C) both ions are highly polarizing due to their small size and high charge.
D) both have virtually identical atomic radii.

Question

Quizplus · Accepted Answer

Beryllium and aluminum are both small in size and have high charges. This makes their ions highly polarizing, which is a property they share. This is the main reason why these elements have similar properties. The other options are not accurate because beryllium has a much higher electron affinity compared to aluminum and their ionization energies are not almost identical. Additionally, their atomic radii are not virtually identical either, as beryllium has a smaller atomic radius compared to aluminum.
