Which group of the periodic table contains only metals

Options

A. IIA
B. IB
C. IA
D. All of these

Explanation

To determine which group of the periodic table contains only metals, we can analyze the groups systematically.

### Step-by-Step Solution:

1. **Identify the Groups**: The periodic table is divided into groups (columns) and periods (rows). Each group contains elements with similar properties.

2. **Examine Group 1 (Alkali Metals)**:
- Group 1 consists of Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).
- All these elements are metals.

3. **Examine Group 2 (Alkaline Earth Metals)**:
- Group 2 includes Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
- All these elements are also metals.

4. **Examine Group 11 (Transition Metals)**:
- Group 11 contains Copper (Cu), Silver (Ag), and Gold (Au).
- These are also metals.

5. **Conclusion**:
- Group 1 (Alkali Metals), Group 2 (Alkaline Earth Metals), and Group 11 (Transition Metals) all consist solely of metals.
- Therefore, the groups that contain only metals are Group 1, Group 2, and Group 11.

### Final Answer:
The groups of the periodic table that contain only metals are Group 1 (Alkali Metals), Group 2 (Alkaline Earth Metals), and Group 11 (Transition Metals).
