Answer 2

Carbon has several allotropes or "appearances" that we've all seen. It is graphite that is black and it gets on your fingers. Pencil lead is graphite. On the other hand, diamondis a much-sought-after gem of story and legend. It is a hard crystal (the hardest natural substance we know), and it comes in just enough different colors to keep us digging into the earth to find more. We are probably all fairly familiar with the black residue of some fires, and soot is the name we give the stuff. There are a couple of more exotic forms of carbon, and you can read about them and these "regular" forms of carbon in the Wikipedia article on this element. A link to the post can be found below.

Answer 3

Carbon comes in two forms. The most common is graphite- the 'lead' you find in pencils that rubs off onto paper. It is black, slippery and brittle. The second form is diamond! Diamond and Graphite are both carbon, but the difference is that the atoms are arranged differently - they are 'allotropes' of Carbon. In graphite, the atoms are arranged in sheets that can slide around easily; this is how pencils work, by the sheets of atoms rubbing onto the paper. In diamond, the atoms are held in a regular giant lattice, held together really tight in a crystal, so diamond is really hard.

Answer 4

Carbon is a solid.
