Question

Match the atomic numbers given in column I with the block in which the element is palced in column II and mark the appropriate choice.

	Column I (Atomic number)		Column II (Block)
(A)	62	(i)	d – block
(B)	47	(ii)	p- block
(C)	56	(iii)	F –block
(D)	53	(iv)	S - block

• A. (A)$\rightarrow$ (iii), (B)$\rightarrow$ (i), (C)$\rightarrow$ (iv), (D)$\rightarrow$ (ii)
• B. (A)$\rightarrow$ (i), (B)$\rightarrow$ (ii), (C)$\rightarrow$ (iii), (D)$\rightarrow$ (iv)
• C. (A)$\rightarrow$ (ii),(B)$\rightarrow$ (iv), (C)$\rightarrow$ (i), (D)$\rightarrow$ (iii)
• D. (A)$\rightarrow$ (iv), (B)$\rightarrow$ (i),(C)$\rightarrow$ (ii), (D)$\rightarrow$ (iii)

Answer 1

Answer: (A)

(A)$\rightarrow$ (iii), (B)$\rightarrow$ (i), (C)$\rightarrow$ (iv), (D)$\rightarrow$ (ii)

Answer 2

: (1) Z = 62 - $4f^{6}5d^{o}6s^{2}$ (f –block)

(2) Z = 47 - $4f^{10}5s^{1}$ (d – block)

(3) Z = 56 - $6s^{2}$

(4) Z = 53 - $5s^{2}5p^{5}$ (p –block)
