Which term describes an attraction between a positive metal ion and the surrounding electrons?

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

Answer: (A)

Metallic bonding is the attraction between positively charged metal ions and a surrounding cloud of delocalized electrons. In a metal, outer electrons are not bound to any one atom; they move freely, forming a shared electron sea that surrounds the lattice of positive ions. This attraction between the fixed ions and the mobile electrons holds the structure together and explains why metals conduct electricity and heat well, and why they’re malleable and shiny. The term that describes this attraction is metallic bonding. An alloy is simply a mixture of elements, not the mechanism of bonding itself. Bacteria and cells are biological terms and aren’t related to how metals bond.
