Question

Match the column I with column II and mark the appropriate choice.

	Column I		Column II
(A)	3d- Transition series	(i)	Z= 58 to Z = 71
(B)	Lanthanoid series	(ii)	Z = 39 to Z = 48
(C)	Actinoid series	(iii)	Z = 21 to Z = 30
(D)	4d – Transition series	(iv)	Z = 90 to Z = 103

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

Answer 1

Answer: (C)

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

Answer 2

: (1) 3d – transition series, Z = 21 (Sc) to Z = 30(Zn)

(2) Lanthanoid series, Z = 58 (Ce) to Z = 71 (Lu)

(3) Actinoid series, Z = 90 (Th) to Z = 103 (Lr)

(4) 4d- transition seres, Z = 39 (Y) to Z = 48 (Cd)
