Classification Of Elements And Periodicity In Properties Question 6

Question 6 - 31 January - Shift 1

$Nd^{2+}=$

(1) $4 f^{2} 6 s^{2}$

(2) $4 f^{4}$

(3) $4 f^{3}$

(4) $4 f^{4} 6 s^{2}$

Show Answer

Answer: (2)

Solution:

Formula: Electronic configuration

$Nd(60)=[Xe] 4 f^{4} 5 d^{0} 6 s^{2}$

$Nd^{2+}=[Xe] 4 f^{4} 5 d^{0} 5 s^{0}$
