Metallic crystals are soluble in________________?
Correct answer: C. Fused metal
- A. Polar solvent
- B. Non polar solvent
- C. Fused metal
- D. None
Explanation
Metallic crystals dissolve in molten or fused metals because metallic bonding permits metal atoms to mix and form alloys. Ordinary polar and non-polar solvents generally do not dissolve a metallic lattice. The likely mistake is choosing a non-polar solvent because metals are not ionic, but metallic bonding is not disrupted by ordinary molecular solvents.

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.
