||Compare and contrast the chemical and physical properties of KCl and CCl4, and compare and contrast how the chemical bonding model can be used to account for these properties.
||Why is the dipole moment of NaCl extremely large?
||Explain why CO has a dipole moment but CO2 does not.
||Explain why an atom with a high ionization energy is expected to have a high electronegativity. Explain why an atom with a high electron affinity is expected to have a high electronegativity.
||Would you predict that a Kr atom has high electronegativity or low electronegativity? Predict the relative electronegativity of Kr and F.
||Explain why S has a greater electronegativity than P but a smaller electronegativity than O.
||N atoms have a high electronegativity. However, N atoms have no electron affinity, meaning that N atoms do not attract electrons. Explain how and why these facts are not inconsistent.
||Explain why compounds formed from elements with large differences in electronegativities are ionic.
||Explain why ionic compounds have much higher melting points than covalent compounds.
