Question

Match the following statements

$\begin{array}{cc}\text{(a)f block elements}& \left(i\right)Group1and2\\ \text{(b)d block elements}& \left(ii\right)Group13to17\\ \text{(c)p block elements}& \left(iii\right)Group3to12\\ \text{(d)s block elements}& \left(iv\right)LanthanidesandActinides\end{array}$

• A. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii).
• B. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i).
• C. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i).
• D. (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii).

Answer 1

The correct option is B

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i).

Group 1 and 2 elements are considered as s block elements.
Group 3 to 12 elements are considered as d block elements.
Group 13 to 17 elements are considered as p block elements. Lanthanides and Actinides are grouped as f block elements.

Each block denotes the name of the orbital which contains the last electron.
