Which statement is false?

Molecular solids generally have lower melting points than covalent solids.

Metallic solids exhibit a wide range of melting points because metallic bonds cover a wide range of bond strength.

The metallic solid can be viewed as positive ions closely packed in a sea of valence electrons.

Most molecular solids melt at lower temperatures than metallic solids.

The interactions among the molecules in molecular solids are generally stronger than those among the particles that define either covalent or ionic crystal lattices.
