An attraction between a positive metal ion and the many electrons surrounding it.

An attraction between a positive metal ion and the many electrons surrounding it.

• A. Alloy
• B. Polar bond
• C. Metallic bond
• D. Bacteria

Answer: (C)

Metallic bonding is the attraction between positively charged metal ions and the sea of delocalized electrons that surround them. In a metal, some electrons are not tied to any single atom and can move freely. The electrostatic pull between these mobile electrons and the fixed positive metal cores holds the atoms together in a lattice, creating the metallic bond. This description matches the idea of an attraction between a positive metal ion and the many electrons around it. An alloy is just a mixture of elements, not a specific bonding type. A polar bond involves unequal sharing of electrons between two atoms, creating partial charges, not a lattice of metal ions and a sea of electrons. Bacteria are unrelated to this chemical concept.
