a. Carbon is the non-metal which is found as diamond, graphite and coal in free state.
- Carbon is the atom which makes diamond, graphite and coal.
- All these structures are made of the same non-metal yet are so different from each other because of the tendency of carbon atom to change its arrangement patterns.
- In the case of graphite, carbon atoms link to form a sheets of carbon atoms.
- On the other hand, in a diamond atom a carbon atom strongly bonds to four other carbon atoms.
