Metals belonging to the same group in the periodic table are

Options

A. Magnesium and Sodium
B. Magnesium and Copper
C. Magnesium and Barium
D. Magnesium and Potassium

Answer

To determine which metals belong to the same group in the periodic table, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Groups in the Periodic Table**:
- The periodic table is organized into groups (columns) and periods (rows). Metals are primarily found in groups 1 (alkali metals) and 2 (alkaline earth metals), as well as in the d-block (transition metals).

2. **List the Metals in Each Group**:
- **Group 1 (Alkali Metals)**: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), Francium (Fr).
- **Group 2 (Alkaline Earth Metals)**: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra).

3. **Analyze the Given Options**:
- The question provides four pairs of metals, and we need to check which pair belongs to the same group.
- **Option 1**: Lithium and Magnesium
- **Option 2**: Magnesium and Copper
- **Option 3**: Magnesium and Barium
- **Option 4**: Magnesium and Potassium

4. **Check Each Pair**:
- **Option 1**: Lithium (Group 1) and Magnesium (Group 2) - Not the same group.
- **Option 2**: Magnesium (Group 2) and Copper (D-block) - Not the same group.
- **Option 3**: Magnesium (Group 2) and Barium (Group 2) - Same group.
- **Option 4**: Magnesium (Group 2) and Potassium (Group 1) - Not the same group.

5. **Conclusion**:
- The only pair of metals that belong to the same group is **Magnesium and Barium** (Option 3).

### Final Answer:
The metals belonging to the same group in the periodic table are **Magnesium and Barium**.
