The existence of an element in more than one crystalline form is called
Correct answer: B. Allotropy
- A. Isomerism
- B. Allotropy
- C. Anistropy
- D. All of these options are correct
Explanation
Allotropy, or allotropism, is the property of some elements to exist in two or more different forms in the same physical state, known as allotropes of the elements. Allotropes are different structural modifications of an element the atoms of the element are bonded together differently. Examples are diamond and graphite, which are both allotropic forms of carbon.

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.
