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.
