Pure copper can be bent and shaped easily. Which statement explains why pure copper can be bent and shaped easily?
The atoms are arranged in molecules that can slide over each other
The atoms are arranged in layers that can slide over each other
The delocalised electrons can slide over the layers of copper atoms
The atoms are all the same size so the metallic bonds are very weak
