b) They can be drawn out into wires
c) They make a ringing noise when struck
d) They are good conductors of heat and electricity

7. In a metallic structure why can layers of metal ions slide over each other?

a) Because metallic bonding is relatively weak
b) Because of the presence of ionic bonding
