1. Which property is NOT typical of metals?
- A. Good conductor of electricity
- B. Malleable
- C. Low melting point
- D. Ductile
2. What are delocalised electrons?
- A. Electrons fixed to one atom
- B. Electrons free to move through the structure
- C. Electrons in the nucleus
- D. Electrons lost during ionic bonding
3. Why can metals be hammered into shape without shattering?
- A. Because they have no bonds between atoms
- B. Because layers of atoms can slide over each other while metallic bonding holds the structure together
- C. Because metals are liquid at room temperature
- D. Because metallic bonds break and reform as separate molecules
4. Which best explains why metals conduct electricity?
- A. Ions vibrate rapidly
- B. Delocalised electrons carry charge through the structure
- C. Metals have low density
- D. Metal atoms share electrons in covalent bonds
5. A student says metals conduct electricity because their atoms are 'free to move.' Why is this an incomplete answer for full marks?
- A. Because it is the delocalised electrons, not whole atoms, that move to carry charge
- B. Because metals do not conduct electricity
- C. Because ions never move in metals
- D. Because only liquid metals conduct electricity
