Question

a model of the electron cloud in the hydrogen fluoride molecule, hf, is shown above. which of the following is directly supported by the model? the electronegativity of fluorine is greater than the electronegativity of hydrogen. the atomic radius of hydrogen is the same as the atomic radius of fluorine. the ionic radius of the hydrogen ion is greater than the ionic radius of the fluorine ion. the ionization energy of fluorine is greater than the ionization energy of hydrogen.

Explanation:

The electron - rich region around fluorine in the HF molecule model indicates that fluorine attracts the bonding electrons more strongly. This is due to fluorine having a higher electronegativity than hydrogen. Atomic radius, ionic radius, and ionization energy are not directly observable from this electron - cloud model.

Answer:

The electronegativity of fluorine is greater than the electronegativity of hydrogen.
