| What is a crystal lattice? |
|
Definition
| a 3-D geometric arrangement of particles in which each positive ioin is surrounded by negative ions and each negative ion is surrounded by positive ions; vary in shape due to sizes and relative numbers of the ions bonded. Is very rigid |
|
|
Term
|
Definition
| an ionic compound whose aqueous solution conducts electricity |
|
|
Term
|
Definition
| Chemical bond formed by the electrostatic attraction between a cation and an anion |
|
|
Term

|
Definition
| coumpound that contains ionic bonds |
|
|
Term

|
Term
| what is an oxidation number? |
|
Definition
| indicates the number of electrons that an element gains or losses as it bonds |
|
|
Term
| What is a polyatomic ion? |
|
Definition
| an ion made up of two or more atoms bonded together that acts as a single unit with a net charge |
|
|
Term

Term
| What is a delocalized electron? |
|
Definition
| electrons that are free to move around |
|
|
Term
| Explain the electron sea model. |
|
Definition
| Proposes that all metal atoms in a metallic solid contribute their valece electrons to form a "sea" of electrons |
|
|
Term
|
Definition

|
Term
| What is the differece between a substitutional alloy and an interstitial alloy? |
|
Definition
| A substitutional is where some of the atoms in the original metallic solid are replaced by other metals of similar size. Interstitial alloys are where small holes in a metallic crystal are filled with smaller atoms. Also Substitutional has properties of both metals and Interstitial has a change in physical properties. |
