| An example of allotropy is carbon, which can exist as diamond, graphite, and amorphous carbon. |
| The difference in the arrangement of space in the atoms that make up the structure of an element is called allotropy. |
| Elements exhibiting allotropy include tin, carbon, sulfur, phosphorus, and oxygen. |
| This would be quite in accordance with the chemical notion of allotropy. |
| Thus carbon occurs as the diamond, and as charcoal and plumbago, and is therefore regarded as a substance subject to allotropy. |
| And this hypothesis is entirely in harmony with the phenomena of allotropy. |
