1) How are atoms arranged in pure copper and bronze?
The atoms are arranged in layers. ... The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide over each other. The alloy is harder and stronger than the pure metal.
2. Why is pure copper relatively soft?
In a pure metal, the force needed to make the layers slide over each other is small. This explains why many pure metals are soft. ... The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide over each other.
3. Why is bronze harder?
Bronze is harder than copper as a result of alloying that metal with tin or other metals. Bronze is also more fusible (i.e., more readily melted) and is hence easier to cast. It is also harder than pure iron and far more resistant to corrosion.
