Atomic Structure Question 261
Question: $ C{u^{2+}} $ will have the following electronic configuration
Options:
A) $ 1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{10} $
B) $ 1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{9},4s^{1} $
C) $ 1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{9} $
D) $ 1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{10},4s^{1} $
Show Answer
Answer:
Correct Answer: C
Solution:
Ground state of $ Cu^{29}=1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}3d^{10}4s^{1} $
$ C{u^{2+}}=1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{9} $ .
