Question

1. choose the best answer. which of these make the best conductor of electricity? polar covalent ionic bonding metallic bonding covalent bonding

Explanation:

Metallic bonding features a "sea of delocalized electrons" that are free to move throughout the material, enabling efficient electrical conductivity. Ionic bonding only conducts electricity when ions are mobile (molten/dissolved), while covalent (polar or nonpolar) bonds involve localized electrons that do not allow easy electrical flow.

Answer:

metallic bonding
