The correct Answer is:
To determine the group of element A based on the information provided, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Problem**: The question states that the chloride of an element A gives a neutral solution in water. This means that when the chloride is dissolved in water, it does not affect the pH of the solution. 2. **Analyzing Chlorides**: Chlorides can be classified based on their behavior in water. Some chlorides produce acidic solutions (like those of non-metals), while others produce basic solutions (like those of alkali metals). 3. **Identifying Neutral Solutions**: A neutral solution in water typically indicates that the chloride does not dissociate into strong acids or strong bases. This behavior is characteristic of certain metal chlorides. 4. **Considering Alkali Metals**: Alkali metals (Group 1 elements) such as sodium (Na) and potassium (K) form chlorides (like NaCl and KCl) that are neutral in solution. When these chlorides dissolve in water, they do not produce H⁺ or OH⁻ ions significantly, thus keeping the solution neutral. 5. **Conclusion**: Since the chloride of element A gives a neutral solution in water, we can conclude that element A belongs to the alkali metals, which are located in Group 1 of the periodic table. ### Final Answer: Element A belongs to the **1st group (Alkali Metals)** in the periodic table. ---
