b) iodine  
c) argon  
d) nitrogen  

---

**Explanation:**

1. **Classification**

   - **Element**: Pure substance consisting of one type of atom.
   - **Compound**: Substance formed when two or more chemical elements are chemically bonded together.
   - **Homogeneous mixture**: Mixture with a uniform composition throughout.
   - **Heterogeneous mixture**: Mixture with a non-uniform composition, where the different components are visibly distinct.

2. **Element Categories**

   - **Metal**: Typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
   - **Non-metal**: Not metallic; often lacking the properties of metals; may be gaseous, liquid, or brittle solid.
   - **Metalloid**: Has properties in between those of metals and non-metals.

3. **Monoatomic Element**

   - An element that consists of single atoms not bonded to each other.

This content is designed to test knowledge of basic chemistry concepts including categorization of materials and elements.
