|
|
Term
| Can metallic compounds conduct electricity? Why or why not? |
|
Definition
| Yes, because electrons can move freely between atoms. |
|
|
Term
| What makes metals flexible? |
|

|
Definition
|
|
Term
| Do molecules in covalent compounds conduct electricity? Why or why not? |
|
Definition
| No, because they are not charged. |

|
Definition
|
|
Term
| What do you call a bond in which electrons are shared equally such as with two chlorine atoms forming a chlorine molecule? |
|
Definition
|
|
Term

Definition
|
|
Term
| (T or F) Atoms always share electrons equally. |
|
Definition
|
|
Term
| An unequal sharing of electrons forms what type of bond? |
|
Definition
|
|
Term
| When atoms are the (same or different), the electrons are not shared equally, and create a Polar Covalent Bond. Give an example of a compound with such a bond. |
|
Definition
|
