What are the basic particles of ice crystals?
Correct answer: D. Molecules
- A. Atoms
- B. Anions
- C. Cations
- D. Molecules
Explanation
d) Molecules:This is the correct answer. Ice crystals are formed by the arrangement of water molecules (H2O) in a specific pattern. Each water molecule is made up of two hydrogen atoms and one oxygen atom, held together by covalent bonds. In the solid state of ice, these molecules form a regular, repeating pattern due to hydrogen bonding between adjacent water molecules.

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
