METALLIC BONDING- malleable metals

Question 1

what does malleable mean

Answer 1

it means something can be ‘hammered into shape’

ductile= drawn into wires

Question 2

metals are both malleable and ductile because…

Answer 2

any force applied will move/ slide a layer of ions over each other,
but they will still be in the same environment,
held together by the sode-

Question 3

why is diamond/
ionic substances
not malleable

Answer 3

diamond= the covalent bonds in diamond need to be broken if a layer is to move, and this makes it brittle.

ionic substance= moving a layer causes ions to line up with the same charged ions (eg negative negative).
this causes them to repel each other and the layers to break (=brittle) eg sodium chloride
