⚠️ Common Misconceptions
Misconception 1: "Metals are held together by covalent bonds"
Covalent bonds involve two specific atoms sharing electrons between them in a fixed, directional bond. Metallic bonding is fundamentally different — electrons are not shared between specific pairs of atoms but are delocalised throughout the entire structure. The metallic bond is the non-directional electrostatic attraction between the electron sea and all the positive ions simultaneously.
Misconception 2: "All metals conduct equally well"
Metals vary significantly in their conductivity. Silver is the best conductor, then copper, then gold, then aluminium. The differences arise from how many electrons each atom contributes to the delocalised sea and how closely packed the ions are. Copper is commonly used for wiring because it balances excellent conductivity with relatively low cost.
Misconception 3: "Metals can only conduct electricity, not heat"
Metals conduct BOTH electricity and heat through the same mechanism — mobile electrons. Thermal conductivity and electrical conductivity in metals are therefore related (described by the Wiedemann-Franz law at A-level). This is why copper is used for both electrical wires AND cooking pans.
