Why are metals bent and shaped?
Metals are malleable – they can be bent and shaped without breaking. This is because they consist of layers of atoms that can slide over one another when the metal is bent, hammered or pressed.
Why can metal be hammered without breaking?
Each positive metal ion is attracted to the negatively charged delocalised electrons. Metals are malleable. This means that they can be hammered or pressed into different shapes without breaking. They are also ductile, which means that they can be drawn out into thin wires without breaking.
