Question:Question 1 (B is incorrect) Why do ionic compounds form?

Question:Question 1 (B is incorrect)

Why do ionic compounds form? (as opposed to molecular compounds)

A) The low electronegativity of metals and high electronegativity of nonmetals cause a localization of valence electrons on the less electronegative atom

B) The high electronegativity of metals and low electronegativity of nonmetals cause a localization of valence electrons on the less electronegative atom

C) The low electronegativity of metals and high electronegativity of nonmetals cause a localization of valence electrons on the more electronegative atom

D) The high electronegativity of metals and low electronegativity of nonmetals cause a localization of valence electrons on the more electronegative atom

Question 2 (D is incorrect)

What sort of ions would give the lowest melting point for the ionic compound?

A) Smaller size and larger charge

B) Larger size and smaller charge

C) Larger size and larger charge

D) Smaller size and smaller charge

Question 3 (C is incorrect) 

How would the strength of the interactions (i.e. potential energy) affect solubility of ionic compounds?

A) Stronger ionic interactions (ion-ion) and weaker solvation interactions (ion-water) would cause the ionic compound to be more soluble in water, due to a decrease in potential energy

B) Stronger ionic interactions (ion-ion) and weaker solvation interactions (ion-water) would cause the ionic compound to be less soluble in water, due to an increase in potential energy

C) Weaker ionic interactions (ion-ion) and stronger solvation interactions (ion-water) would cause the ionic compound to be less soluble in water, due to a decrease in potential energy

D) (a) and (c
