SATHEE: Atomic Structure Question 261

Atomic Structure Question 261

Question: $C u^{2 +}$ will have the following electronic configuration

Options:

A) $1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{10}$

B) $1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{9}, 4 s^{1}$

C) $1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{9}$

D) $1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{10}, 4 s^{1}$

Show Answer

Answer:

Correct Answer: C

Solution:

Ground state of $C u^{29} = 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{1}$

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