A) 5s
B) 4s
C) 4d
D) 4 \[f\]
Correct Answer: D
Solution :
Key Idea Principal quantum number (n) determines the main energy level or shell. Azimuthal quantum number \[(l)\] determines the sub-shell. Value of \[(l)\] 0 1 2 3 Sub-shell s p d f Magnetic quantum number (m) refers to the different orientations of the orbital in space. Spin quantum number (s) describes the spin orientation of the electron. Here, \[n=4,\,\,l=3,\,\,m=2\] and \[s=\frac{1}{2}\] Therefore, the correct designation of electron is \[4f\].You need to login to perform this action.
