Question

Which atom is most likely to form a metallic bond?

aluminum (Al)
helium (He)
phosphorus (P)
carbon (C)

Answer 1

Aluminum (Al) is the atom most likely to form a metallic bond. Metallic bonds typically occur in metals, which are characterized by a lattice structure of positively charged ions surrounded by a "sea" of delocalized electrons. Aluminum is a metal, while helium (He) is a noble gas, and phosphorus (P) and carbon (C) are nonmetals. Therefore, among the options given, aluminum is the one that forms metallic bonds.
