Based on the data in the table above, which of the following correctly predicts the relative electronegativity of the elements X, Y, and Z, and provides the correct reason?
X > Y > Z because smaller elements have a stronger coulombic attraction between the nucleus and valence electrons
X > Y > Z because smaller elements have a weaker coulombic attraction between the nucleus and valence electrons
Z > Y > Z because larger elements have a stronger coulombic attraction between the nucleus and valence electrons
Z > Y > Z because larger elements have a stronger coulombic attraction between the nucleus and valence electrons

Which of the following correctly identifies which has the higher electronegativity, Sn or Te, and supplies the best justification?
Sn, because of its higher nuclear charge
Sn, because of the closer distance between nucleus and bonded electrons
Te, because of its higher nuclear charge
Te, because of the closer distance between nucleus and bonded electrons

The table above shows the number of protons, atomic radius, and the electronegativity of several elements. Which of the following best helps explain the deviation of the electronegativity of krypton from the overall trend?
The atomic radius of krypton is smaller than the atomic radius of bromine.
The atomic radius of krypton is smaller than the atomic radius of bromine.
There is repulsion between the electrons in krypton’s valence shell.
The valence shell in krypton is full meaning it is unreactive.
