Question
- A. The rigid structure prevents movement.
- B. The layers of ions can slide over each other.
- C. The ionic bonds are too strong.
- D. The electrons are fixed in place.
Answer
The layers of ions can slide over each other.
Explanation
Ductility in metals is a result of their ability to deform under stress. The layers of positive ions in the metallic lattice can slide over each other due to the delocalised electrons, allowing the metal to be drawn into wires.
Common mistake
Misunderstanding Malleability
Students often confuse malleability with ductility, thinking they are the same property.
Malleability refers to the ability of a metal to be hammered or rolled into thin sheets, while ductility is the ability to be drawn into wires. To explain malleability using metallic bonding, state that the layers of positive ions in a metal can slide over each other due to the presence of delocalised electrons, which allows the metal to change shape without breaking. This is because the metallic bond remains intact as the delocalised electrons can move with the ions.
