Question

An allotrope of carbon that is as tensile as steel is?

Answer 1

Allotropes

• Allotropes are two or more forms of the same elements that exist in the same physical state (solid, liquid, or gas) but have physical and chemical properties that differ from one another.
• Carbon exhibits many allotropic forms. Diamond and graphite are two well-known crystalline forms of carbon.

Allotrope of carbon that is as tensile as steel

• Carbon nanotubes, allotropes of carbon, are the strongest materials, with the highest tensile strength.
• The range of carbon nanotube is $100–200\text{GPa}$.

So, an allotrope of carbon that is as tensile as steel is carbon nanotubes.
