The bond order between two atoms of this element differentiates alkynes from alkanes.
The bond order between two atoms of this element differentiates alkynes from alkanes. The 2010 Nobel Prize in Physics was awarded for the formation of a twoÂ­dimensional, hexagonal allotrope of this element that forms (*) fullerenes like the buckyÂ­ball. Another allotrope of this element has a Mohs hardness of 10. For 10 points, name this element found in graphite and diamond that has atomic number 6 and symbol C
