Melt it or dissolve it in water |
|
|
Term
Can solid ionic compounds conduct electricity? |
|
Definition
|
|
Term
Can metallic compounds conduct electricity? Why or why not? |
|
Definition
Yes, because electrons can move freely between atoms. |
|
|
Term
What makes metals flexible? |
|

The fact that their atoms can slide past each other without their bonds breaking. |
|
|
Term

|
Definition
|
|
Term
Most covalent compounds have relatively (low or high) melting points. |
|
Definition
|
|
Term
Do molecules in covalent compounds conduct electricity? Why or why not? |
|
Definition
No, because they are not charged. |
|
|
Term
Do Covalent Bonds share electrons or transfer electrons? |
|
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
Covalent bonds form when atoms share pairs of ________ electrons. |
|
Definition
|
|
Term

|
Definition
|
|
Term

|
Definition
Triple, then double, single is weakest |
|
|
Term

|
Definition
|
|
Term
_________bonds form when atoms share pairs of valence electrons. |
|
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
|
|
