Question
Which of the following correctly compares periodic properties of two elements and provides an accurate explanation for that difference?
A.
The first ionization energy of Al is greater than that of B because Al has a larger nuclear charge than B does.
B.
The first ionization energy of F is greater than that of O because O has a higher electronegativity than F has.
C.
The atomic radius of Ca is larger than that of Mg because the valence electrons in Mg experience more shielding than the valence electrons in Ca do.
D.✓ Correct
The atomic radius of Cl is smaller than that of S because Cl has a larger nuclear charge than S does.
