Atomic Structure Question 248
Question: For $ n=3 $ energy level, the number of possible orbitals (all kinds) are
Options:
A) 1
B) 3
C) 4
D) 9
Show Answer
Answer:
Correct Answer: D
Solution:
When $ n=3 $ shell, the orbitals are $ n^{2}=3^{2}=9 $ . No. of electrons $ =2n^{2} $
Hence no. of orbital $ =\frac{2n^{2}}{2}=n^{2} $ .
