Question
Explain why layers of atoms in pure metals can slide, allowing metals to be bent and shaped.
Answer
In pure metals, the atoms are arranged in regular layers. When a force is applied, these layers can slide over each other due to the metallic bonding, which involves a sea of delocalised electrons that allows the atoms to move without breaking the bonds.
Explanation
This answer is strong because it clearly describes the arrangement of atoms in pure metals and the role of metallic bonding in allowing the layers to slide. The question tests the student's understanding of the structure and properties of metals.
Common mistake
Misunderstanding Metal Structure
Students often think that the layers of atoms in pure metals cannot slide because they are tightly packed.
Emphasize that the regular arrangement of atoms in pure metals allows layers to slide over each other, which is what enables metals to be bent and shaped.
