| Question | Answer |
|---|---|
| what is the relationship between lattice energy and charge? | as the ionic charges increase, lattice energy also increases |
| what is the relationship between lattice energy and the distance between ions? | lattice energy inversely proportional to the distance between ions |
| what happens to lattice energy when the ions shift over an atom? | the positive ions line up with the other positive ions and the negative line up with the negative and they shatter |
| what is an empirical formula? | simplest whole number ratio of a compound |
| define pseudo-noble gas configuration? | elements that are stable because they partially fill the d-block |
| fill in the blanks: in an ionic bond, BLANK electrons are BLANK usually from the BLANK to the BLANK | valence, transferred, metal, nonmetal |
| what is a chemical bond? | the force that holds 2 atoms together |
| what is a metallic bond? | the attraction of a metallic cation for delocalized electrons |
| what is the definition of the electron sea? | all metal atoms in a metallic solid contribute their valence electrons to form a sea of electrons |
| what is the definition of a crystal lattice? | the strong attractions among the positive ions in an ionic compounds |
| what are delocalized electrons? | electrons that are free to move |
| what is a metallic bond? | the attraction of a metallic cation for a delocalized electron |
| true or false: ionic crystals have high melting AND boiling points | true |
