What is Allotropes?
Allotropes are different structural modifications of the same element in the same physical state, having different physical properties. Allotropy is a property of elements (not compounds). Famous examples include the allotropes of carbon (diamond, graphite, fullerene, graphene), phosphorus (white, red, black), oxygen (O₂ vs. ozone O₃), and sulfur (rhombic vs. monoclinic).

Frequently Asked Questions
Allotropes are different structural modifications of the same element in the same physical state, having different physical properties. Allotropy is a property of elements (not compounds). Famous examples include the allotropes of carbon (diamond, graphite, fullerene, graphene), phosphorus (white, red, black), oxygen (O₂ vs. ozone O₃), and sulfur (rhombic vs. monoclinic).
Diamond in cutting tools and jewellery; graphite as lubricant, electrode, and pencil material; fullerenes in nanotechnology and drug delivery; white phosphorus in incendiary devices (military/safety matches); sulfur allotropes in rubber vulcanisation; ozone in stratospheric UV protection
Depends on specific allotrope. White phosphorus is highly toxic and pyrophoric (ignites spontaneously in air). Ozone is a powerful oxidising agent and lung irritant. Diamond is safe but extremely hard. Always check safety data for the specific allotropic form.
