Question
Which of the following contain carbon atoms?
- Diamond
- Graphite
- Fullerene
- All the above
Hint:
Carbon has a lot of allotropes. Some are used to make ornaments and some is used in pencil as lead.
The correct answer is: All the above
The correct option is d)All of the above.
Fullerenes are carbon allotropes whose molecules are composed of carbon atoms joined by single and double bonds to form a closed or partially closed network of fused rings of 5-7 atoms.
Graphite is a crystalline form of elemental carbon. It is made up of layers of graphene. Graphite forms when carbon is subjected to the intense heat and pressure of the Earth's crust and upper mantle.
Diamond is a solid of the carbon element, whose atoms are arranged in a crystal structure called cubic diamond.
