Question

Match the LIST-I with LIST-II: 

LIST-I	LIST-II
A. Chlorine B. Calcium C. Sodium D. Sulfur	I. CHALCOGEN II. ALKALI METAL III. HALOGENS IV. ALKALINE EARTH METALS

Choose the correct answer from the options below:

• A. A-IV, B-III, C-I, D-II
• B. A-III, B-II, C-I, D-IV
• C. A-III, B-IV, C-II, D-I
• D. A-I, B-II, C-III, D-IV

Hint:

Periodic table group names:
• Group 1 = Alkali metals
• Group 2 = Alkaline earth metals
• Group 16 = Chalcogens
• Group 17 = Halogens

Answer 1

The Correct Option is C

Concept: Elements in the periodic table are arranged into groups according to similar electronic configuration and chemical properties. Important groups involved here:
• Group 1 = Alkali metals
• Group 2 = Alkaline earth metals
• Group 16 = Chalcogens
• Group 17 = Halogens

Step 1: Identify the group of Chlorine. Chlorine (\(\mathrm{Cl}\)) belongs to Group 17. Group 17 elements are called: \[ \boxed{\text{Halogens}} \] Therefore: \[ A \rightarrow III \]

Step 2: Identify the group of Calcium. Calcium (\(\mathrm{Ca}\)) belongs to Group 2. Group 2 elements are called: \[ \boxed{\text{Alkaline Earth Metals}} \] Therefore: \[ B \rightarrow IV \]

Step 3: Identify the group of Sodium. Sodium (\(\mathrm{Na}\)) belongs to Group 1. Group 1 elements are called: \[ \boxed{\text{Alkali Metals}} \] Therefore: \[ C \rightarrow II \]

Step 4: Identify the group of Sulfur. Sulfur (\(\mathrm{S}\)) belongs to Group 16. Group 16 elements are called: \[ \boxed{\text{Chalcogens}} \] Therefore: \[ D \rightarrow I \]

Step 5: Write the complete matching. Thus: \[ \boxed{ A-III,\ B-IV,\ C-II,\ D-I } \]

Step 6: Match with the options. The correct option is: \[ \boxed{(3)} \] Additional Understanding: Important periodic groups:
• Group 1 \( \rightarrow \) Alkali metals
• Group 2 \( \rightarrow \) Alkaline earth metals
• Group 16 \( \rightarrow \) Chalcogens
• Group 17 \( \rightarrow \) Halogens
• Group 18 \( \rightarrow \) Noble gases Final Conclusion: Correct matching: \[ \boxed{ A-III,\ B-IV,\ C-II,\ D-I } \] Hence, the correct answer is: \[ \boxed{(3)} \]
