Bronze is an alloy of copper (\(\text{Cu}\)) and tin (\(\text{Sn}\)), while carbon steel is an alloy of iron (\(\text{Fe}\)) and carbon (\(\text{C}\)). The atomic radius of \(\text{Cu}\) is \(128\text{ pm}\), \(\text{Sn}\) is \(140\text{ pm}\), \(\text{Fe}\) is \(126\text{ pm}\), and \(\text{C}\) is \(77\text{ pm}\). Which of the following pairs correctly identifies the alloy classification of bronze in Column 1 and the particulate-level explanation for why carbon steel is less malleable than pure iron in Column 2?
