Which of the following correctly compares periodic properties of two elements and provides an accurate explanation for that difference? The first ionization energy of Al is greater than that of B because Al has a larger nuclear charge than B does. A The first ionization energy of F is greater than that of O because O has a higher electronegativity than F has. B 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. C The atomic radius of Cl is smaller than that of S because Cl has a larger nuclear charge than S does.
