The type of intermolecular forces (forces between the particles) present in solid mercury is:
Correct answer: C. Metallic bonds
- A. Covalent bonds
- B. Ionic bonds
- C. Metallic bonds
- D. H-bonds
Explanation
Solid mercury, or simply mercury (Hg) in its solid state, is an example of a metal. In metals, the bonding between atoms is primarily due to metallic bonds. Metallic bonds occur between metal atoms and are characterized by the delocalization of electrons. In a metallic bond, the valence electrons of the metal atoms are loosely held and can move freely throughout the solid lattice, creating a "sea" of delocalized electrons. This electron delocalization gives rise to several unique properties of metals, such as high electrical and thermal conductivity and malleability.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
