Question

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

	Column I (Atom)		Column II (No. of unpaired electrons)
(A)	15P	(i)	6 unpaired electrons
(B)	24Cr	(ii)	2 unpaired electrons
(C)	26Fe	(iii)	3 unpaired electrons
(D)	14Si	(iv)	4 unpaired electrons

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

Answer 1

Answer: (C)

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

Answer 2

: $15P = \lbrack Ne\rbrack 3s^{2}3p^{3}$

$24Cr = \lbrack Ar\rbrack 4s^{1}3d^{5}$

$26Fe = \lbrack Ar\rbrack 4s^{2}3d^{6}$

$14Si = \lbrack Ne\rbrack 3s^{2}3p^{2}$
