Allotropy in elements: Diamond is an allotropic form of which element? Allotropes are different structural forms of the same chemical element with distinct physical properties. Choose the correct element.

Given data

• Diamond is being compared as an allotropic form.

Concept/Approach
Allotropy refers to different structural forms of the same element. Carbon exhibits prominent allotropes: diamond (sp³ lattice), graphite (sp² sheets), graphene, fullerenes, etc.

Step-by-step reasoning
Diamond consists of a 3D tetrahedral network of carbon atoms (sp³ hybridization), giving it exceptional hardness and high thermal conductivity.

Common pitfalls
Confusing with silicon or germanium, which also form covalent networks but are not the substance of diamond.

Final Answer
Carbon
