Question
Explain the difference.
Crystalline and non-crystalline forms of carbon.
Solution
| Crystalline carbon | Non-crystalline carbon |
| A crystalline form has a regular and definite arrangement of atoms. | A Non-crystalline form does not have the regular arrangement of atoms. |
| Their melting point and boiling point are high and specific. | It melts at very high temperatures. |
| Crystalline carbon is a very hard substance. | Non-crystalline carbon is brittle. |
| A crystalline form has a definite geometrical shape, sharp edges and plane surfaces. | They are amorphous, hence, they do not have definite geometrical shape. |
| Diamond, graphite and fullerene are different crystalline forms of carbon. | Coal, charcoal and coke are different non-crystalline/amorphous forms of carbon. |
