The existence of a substance in more than one solid modifications is known as__________

(a) isomorphism

(b) Polymorphism

(c) Amorphism

(d) Allotropy

Expert Solution

Answer : (b) Polymorphism

Explanation :

The existence of a substance in more than one crystalline structure form is known as polymorphism. For example, Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic.

b) Polymorphism
