Quick check
Answer each question before opening the answer.
Describe metallic bonding.
A lattice of positive metal ions surrounded by a 'sea' of delocalised electrons, held together by electrostatic attraction.
Why are metals good conductors and malleable?
Delocalised electrons are free to move and carry charge; the layers of ions can slide over each other.
