Which is the BEST example of a metallic bond?
ASodium chloride
BDiamond carbon network
CWater molecules attracted to each other
DSea of electrons in copper
Answer & Solution
Correct answer: A. Sodium chloride
1. Metallic bonding is the attraction between metal cations and a 'sea' of delocalised electrons.
2. Copper is a typical metal; its valence electrons roam freely.
3. This sea of electrons holds the Cu+ ions together.
4. So copper is the classic example.
