The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Non-Metals**: Non-metals are elements that typically have low melting and boiling points. This is a general characteristic of non-metals. 2. **Identifying the Exception**: The question asks for an exception to this rule. We need to find a non-metal that has high melting and boiling points. 3. **Considering Allotropes of Carbon**: Among non-metals, carbon exists in different forms known as allotropes. The most common allotropes of carbon are diamond and graphite. 4. **Analyzing Graphite**: Graphite is one of the allotropes of carbon. Unlike most non-metals, graphite has a high melting point and boiling point. 5. **Understanding Graphite's Structure**: The structure of graphite consists of hexagonal layers of carbon atoms. Within each layer, carbon atoms are bonded covalently, which creates strong bonds that require a significant amount of energy to break. 6. **Conclusion**: Therefore, the answer to the question is "graphite," as it is the non-metal exception that has very high melting and boiling points. **Final Answer**: Graphite ---
