Atomic Structure Question 497
Question: Number of electron having the quantum numbers $ n=4,,\ell =0,,s=-\frac{1}{2} $ in $ Z{n^{+2}} $ ion is/are:
Options:
A) 1
B) 0
C) 2
D) 5
Show Answer
Answer:
Correct Answer: B
Solution:
- Electronic configuration of $ Z{n^{2+}} $ ion is $ 1s^{2}2s^{2} $
$ 2p^{6}3s^{2}3p^{6}3d^{10} $ so no electron inorbitals.
