Question

Match the LIST-I with LIST-II

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

Hint:

Memory Tip:
• s-block \(\rightarrow\) Groups 1 and 2
• d-block \(\rightarrow\) Transition elements
• f-block \(\rightarrow\) Lanthanides and Actinides
• p-block \(\rightarrow\) Metalloids and non-metals

Answer 1

The Correct Option is B

Concept:
Elements are classified into blocks based on the subshell receiving the last electron.
Step 1:
Alkaline earth metals belong to Group 2. Thus they are: \[ \boxed{\text{s-block}} \] Hence: \[ A \rightarrow I \]
Step 2:
Transition elements involve filling of \(d\)-orbitals. Thus: \[ B \rightarrow III \]
Step 3:
Transuranic elements belong to actinide series: \[ C \rightarrow IV \] Metalloids are mainly found in p-block: \[ D \rightarrow II \]
Step 4:
Final matching: \[ A-I,\quad B-III,\quad C-IV,\quad D-II \] Closest correct option is: \[ \boxed{\text{Option (2)}} \]
