1. What is metallic bonding?
- A. The transfer of electrons between atoms
- B. The sharing of electron pairs between atoms
- C. A lattice of positive ions surrounded by delocalised electrons
- D. An attraction between simple molecules
2. Where do the delocalised electrons in a metal come from?
- A. The nucleus of each atom
- B. The outer-shell electrons of the metal atoms
- C. Electrons transferred from non-metal atoms
- D. They are created during melting
3. What holds a metallic lattice together?
- A. Weak intermolecular forces
- B. Strong electrostatic attraction between positive ions and delocalised electrons
- C. Covalent bonds between neighbouring atoms
- D. Hydrogen bonds
4. How does metallic bonding differ from ionic bonding?
- A. Metallic bonding involves only positive ions and delocalised electrons; ionic bonding involves oppositely charged ions from electron transfer
- B. They are identical
- C. Metallic bonding only occurs in non-metals
- D. Ionic bonding involves delocalised electrons
5. A metal atom's outer electrons become delocalised. What charge does the remaining ion have?
- A. Negative
- B. Neutral
- C. Positive
- D. No charge — it stays an atom
