Step 1
Step 2
Step 3
Explain why other metals are added to aluminium.
Answer
Other metal atoms have different sizes compared to aluminium atoms. This causes distortions in the layers of aluminium atoms, which prevents the layers from sliding over each other easily. As a result, the alloy becomes harder and, therefore, stronger.
Step 4
Compare the bonding within the chains with the forces between the chains in this polymer.
Answer
The bonding within the chains of the polymer consists of strong covalent bonds between the atoms. In contrast, the forces between the chains are weaker intermolecular forces. Consequently, while the chains themselves are robust due to the strong covalent bonds, the overall structure is more flexible because the weaker intermolecular forces allow the chains to move past one another.
