Is carbon ductile malleable and does it have lustre?

Answer 1

Carbon is not ductile or malleable, but it can have luster depending on what form it is in. In most cases it does not, but graphite does have a luster.

Answer 2

Carbon is neither ductile nor malleable as it is a non-metallic element. It does not have lustre inherently; however, certain forms of carbon, such as diamonds, can exhibit a shiny appearance due to their high refractive index.
