Classification Of Elements And Periodicity In Properties Ques 313
Question: Pd has exceptional valence shell electronic configuration of $ 4d^{10}5s^{0} $ . It is a member of-
Options:
A) 5th Period, Group 10
B) 4th Period, Group 12
C) 6th Period, Group 10
D) 5th Period, Group 14
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ 4d^{10}5s^{0} $ is the exceptional configuration of Pd. Its electronic configuration should be $ [ _{36}Kr ]4d^{8},5s^{2}. $ Thus its Period = 5th Group $ =ns+(n-1l)d $ electrons $ =2+8=10 $
