Materilas around us can be classified into __________.

Options

A. Elements and compounds
B. Metals and non-metals
C. Acids and base
D. None of these

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks how materials around us can be classified. This means we need to identify the categories into which these materials can be grouped.

2. **Identifying Options**: The options provided are:
- A) Elements and Compounds
- B) Metals and Non-metals
- C) Acids and Bases
- D) None of these

3. **Analyzing Each Option**:
- **Option A (Elements and Compounds)**: This classification is based on the chemical composition of materials. While it is valid, it does not specifically address the physical properties of materials.
- **Option B (Metals and Non-metals)**: This classification is based on the physical and chemical properties of materials. Metals are typically shiny, good conductors of heat and electricity, while non-metals are dull and poor conductors (with some exceptions).
- **Option C (Acids and Bases)**: This classification is based on the chemical nature of substances, specifically their pH levels. It is not a comprehensive classification for all materials.
- **Option D (None of these)**: This option suggests that none of the classifications are correct, which is not the case.

4. **Choosing the Correct Answer**: Based on our analysis, the most appropriate classification of materials around us is **B) Metals and Non-metals**. This classification encompasses a wide range of materials based on their properties.

5. **Conclusion**: Therefore, the answer to the question "Materials around us can be classified into __________" is **Metals and Non-metals**.
