The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Conductivity**: Conductivity refers to the ability of a material to allow the flow of electric current. This is largely determined by the presence of free-moving charged particles, such as electrons. 2. **Identifying Non-Metals**: Non-metals are elements that generally lack the properties of metals. They are found on the right side of the periodic table and include elements like carbon, sulfur, and oxygen. 3. **Examining Electron Presence**: For a material to conduct electricity, it needs to have free electrons that can move easily. Metals have a lot of free electrons, which is why they are good conductors of electricity. 4. **Analyzing Non-Metals**: Non-metals, on the other hand, do not have free electrons. Their electrons are usually involved in covalent bonds, which means they are not free to move around and carry electric current. 5. **Conclusion**: Since non-metals lack free electrons, they do not conduct electricity well, making them poor conductors. Therefore, the reason non-metals do not conduct electricity is that they do not have free electrons. 6. **Final Answer**: Non-metals do not conduct electricity because they do not have free electrons.
