When an element exist in more than one crystalline forms, it is known as:
Correct answer: E. C and d
- A. Anisotropy
- B. Isomorphism
- C. Allotropy
- D. Polymorphism
- E. C and d
Explanation
Allotropy specifically refers to the existence of an element in two or more different structural forms when they are in the same physical state. For instance, carbon exists as diamond and graphite, which are different allotropes of carbon. Therefore, option c is correct.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
