Show answer
Must show: Reference to layers of positive ions sliding, Bonding not disrupted (delocalised electrons still attract)
Also accept: Layers of metal ions can slide over each other without breaking the metallic bonds.
Common mistakes: Breaking bonds causes the layers to move.; Metals split due to weak forces.

A1 · 1 mark · States that bonding is not disrupted because the delocalised electrons still hold the ions together.
Worked solution
When a metal is hammered, the layers of positive ions can slide over each other. The metallic bonding remains intact because the delocalised electrons move to maintain the attraction between the positive ions, so the metal does not break apart.
