Exploring Bonding Types: Ionic, Covalent, and Metallic

What is the structure of metallic bonding?

• Neutral atoms in a lattice

• Positive ions in a lattice surrounded by protons

• Positive ions in a lattice surrounded by delocalized electrons

• Negative ions in a lattice surrounded by delocalized electrons

Why do metals make good conductors?
