All of the following substances are crystalline except
Correct answer: D. Plastic
- A. Ice
- B. Carbon (diamond)
- C. Sucrose
- D. Plastic
Explanation
Crystalline substances have a well-defined, repeating three-dimensional arrangement of atoms, ions, or molecules.Plastic: Plastic is a polymer and typically does not have a well-defined crystalline structure. Many plastics are amorphous, meaning they lack a repeating and ordered arrangement of molecules.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
