Question:

$\text{Match the atomic numbers in List I with the corresponding groups in List II:}$ $\begin{array}{|c|c|} \hline \text{List-I (Atomic number)} & \text{List-II (Group)} \\ \hline \text{i.} & 52 & \text{P.} & \text{s} \\ \text{ii.} & 37 & \text{Q.} & \text{p} \\ \text{iii.} & 65 & \text{R.} & \text{f} \\ \text{iv.} & 74 & \text{S.} & \text{d} \\ \hline \end{array}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $(\text{i})-\text{Q}, (\text{ii})-\text{P}, (\text{iii})-\text{R}, (\text{iv})-\text{S}$
2. $(\text{i})-\text{Q}, (\text{ii})-\text{P}, (\text{iii})-\text{S}, (\text{iv})-\text{R}$
3. $(\text{i})-\text{S}, (\text{ii})-\text{R}, (\text{iii})-\text{P}, (\text{iv})-\text{Q}$
4. $(\text{i})-\text{R}, (\text{ii})-\text{P}, (\text{iii})-\text{Q}, (\text{iv})-\text{S}$

Solution:

$65 : \text{f - block}$ $37 : [\text{Kr}]5s^1 \rightarrow \text{s - block}$ $52 : [\text{Kr}]5s^24d^{10}5p^4 \rightarrow \text{p - block}$ $74 : [\text{Xe}]6s^24f^{14}5d^4 \rightarrow \text{d - block}$
