Diamond and graphite are both forms of pure carbon. Answer true or false.
Answer
true
- pure carbon
- a substance composed solely of carbon atoms, with no other elements bonded into its lattice
- form of pure carbon
- an allotrope of elemental carbon, i.e. a distinct crystalline/structural arrangement of carbon atoms only
