Metallic bonding
Chemistry · Secondary 4 · Medium · Metallic bonding
Pure copper is soft and can be easily hammered into thin sheets. Which statement, based on metallic bonding, best explains this property?
- Layers of copper ions can slide over each other while remaining attracted to delocalised electrons.
- Copper atoms form strong directional covalent bonds that cannot break.
- Delocalised electrons are fixed in place, so the ions cannot move at all.
- Copper ions repel the delocalised electrons, causing the layers to separate easily.
