Problem
When a small percentage of carbon atoms occupy interstitial sites in an iron lattice to form steel, both the valence-electron concentration and the lattice regularity change. Predict how this modification affects (a) electrical conductivity and (b) malleability relative to pure iron, and justify each prediction using metallic-bonding principles.
