• Hybridization = sp3 FC = 0

• Hybridization = sp2 FC = -1

• Hybridization = sp3 FC = -1

• Hybridization = sp FC = 0

A bond between Cs and Cl would best be described as...

• Ionic because the masses of both atoms are large

• Ionic because the difference in electronegativity is large

• Covalent because the difference in electronegativity is small

• Covalent because the masses of the atoms are dissimilar

Which of the following pairs of atoms/ions are correctly ranked in from greater radii to smaller?

• Br- > I-

• Br- > Br

• Na+ > Na

• Mg > Na

Why does Li require a lower frequency of light to remove an electron compared to O?

• Lithium has a smaller mass so requires a lower frequency of light

• Lithium has a smaller nuclear charge which means less energy is needed to remove an electron

• Lithium has a smaller nuclear charge which means more energy is needed to remove an electron

• Lithium's electrons are more heavily shielded than O's electrons so less energy is needed

The correct electronegativities of H, C, and Cl are respectively...

• 1.2, 2.5, and 3.5

• 2.5, 2.1, and 3.5

• 2.1, 2.5, and 3.0

• 1.2, 2.5, and 3.0
