The metallic bonding model is a __________ lattice arrangement.

Which of the following are properties of metals? (select all that apply)

• Malleable

• Good insulator of electricity

• Good thermal conductor

• Low melting but high boiling point

• Lustrous

What feature of the metallic bonding model allows metals to be malleable?

Metals are such good thermal conductors because

• metal cations vibrate the heat energy along the metal quickly

• electrons transfer the heat energy along the metal quickly

• metal cations prevent the transfer of heat along the metal

• electrons prevent the transfer of heat along the metal

Metals are very hard due to the strong ______________ attraction between the negative electrons and the positive cations.
