Question

Match the following.

\[ \begin{array}{|c|c|c|c|} \hline \text{List-I} & \text{Atomic number} & \text{List-II} & \text{Group} \\ \hline \text{A} & 53 & \text{I} & 16 \\ \hline \text{B} & 34 & \text{II} & 2 \\ \hline \text{C} & 38 & \text{III} & 17 \\ \hline \text{D} & 49 & \text{IV} & 13 \\ \hline & & \text{V} & 7 \\ \hline \end{array} \]
The correct answer is

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

Hint:

Remember these important atomic numbers: \[ 53 \rightarrow \mathrm{I},\; 34 \rightarrow \mathrm{Se},\; 38 \rightarrow \mathrm{Sr},\; 49 \rightarrow \mathrm{In}. \]

Answer 1

The Correct Option is B

Step 1: Identify the elements from their atomic numbers. \[ 53 \rightarrow \mathrm{I} \;(\text{Iodine}) \rightarrow \text{Group }17 \] \[ 34 \rightarrow \mathrm{Se} \;(\text{Selenium}) \rightarrow \text{Group }16 \] \[ 38 \rightarrow \mathrm{Sr} \;(\text{Strontium}) \rightarrow \text{Group }2 \] \[ 49 \rightarrow \mathrm{In} \;(\text{Indium}) \rightarrow \text{Group }13 \]

Step 2: Match with List-2. \[ A \rightarrow \text{III},\qquad B \rightarrow \text{I},\qquad C \rightarrow \text{II},\qquad D \rightarrow \text{IV}. \] Hence, \[ \boxed{\text{A--III,\; B--I,\; C--II,\; D--IV}} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
