Verified step by step guidance1
Understand that melting point is related to the strength of the forces holding atoms or ions together in a solid.
Recall that metallic bonding involves a lattice of metal cations surrounded by a 'sea' of delocalized valence electrons, which creates strong attractive forces throughout the metal.
Compare this to other types of bonding: hydrogen bonding is a weak intermolecular force, ionic bonding involves attraction between ions but is typical of ionic compounds, and covalent bonding involves shared electron pairs between specific atoms.
Recognize that the strong, non-directional metallic bonds allow metals to have high melting points because a lot of energy is required to break these bonds.
Conclude that the high melting points of most metals are primarily due to metallic bonding.
