SATHEE: Atomic Structure Question 282

Atomic Structure Question 282

Question: What is the electronic configuration of $C u^{2 +} (Z = 29)$ of least position

Options:

A) $[A r], 4 s^{1} 3 d^{8}$

B) $[A r], 4 s^{2} 3 d^{10} 4 p^{1}$

C) $[A r], 4 s^{1} 3 d^{10}$

D) $[A r], 3 d^{9}$

Show Answer

Answer:

Correct Answer: D

Solution:

$_{29} C u = [A r], 3 d^{10} 4 s^{1},, C u^{2 +} = [A r], 3 d^{9} .4 s^{0}$ . Ground state of $C u^{29} = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{1}$

$C u^{2 +} = 1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{9}$ .
