- Noun:
- The allotropism of carbon is evident in the contrasting properties of graphite and diamond.
- Scientists study the allotropism of elements like sulfur and phosphorus to understand their varied behaviors.
Advanced Usage
- "Exhibit allotropism": To display the property of having multiple allotropic forms.
