Which of the following best describes a metallic bond?
A
Attraction between polar molecules
B
Transfer of electrons between atoms
C
Sharing of electron pairs
D
Sea of delocalized electrons around metal cations
Correct Answer: Option D — Sea of delocalized electrons around metal cations
Explanation:
Metallic bonding involves a lattice of positive metal cations surrounded by a 'sea' of delocalized electrons, which explains properties like electrical conductivity, malleability, and ductility of metals.
