MCQ
What is not a type of crystal?
- AIonic
- BMetallic
- CCovalent molecular
- ✓Amorphous
✓
Answer
Correct option: D.
Amorphous
Explanation: (D) Amorphous
Crystals tend to have relatively sharp, well-defined melting points because all the component atoms, molecules, or ions are the same distance from the same number and type of neighbours; that is, the regularity of the crystalline lattice creates local environments that are the same.
Thus the intermolecular forces holding the solid together are uniform, and the same amount of thermal energy is needed to break every interaction simultaneously.
Amorphous has different property to crystal.
