Some examples are rubber, glass, pitch, tar, fused silica, plastics, polymers of high molecular mass, etc. Q.6. Which is better crystalline or amorphous? Ans: Crystalline solid is better than amorphous solid. WebMetals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids.
