Show full solutionCorrect option: A
Correct answer
An = 4, l = 3, m = +1, s = + 1/2
Step-by-step explanation
For 4f orbital,
n = 4 and l = 3
Note : ( for s orbital l = 0, for p orbital l = 1, for d orbital l = 2, for f orbital l = 3)
Value of m = + l to - l
Here m = +3 to -3
Value of s = or
n = 4 and l = 3
Note : ( for s orbital l = 0, for p orbital l = 1, for d orbital l = 2, for f orbital l = 3)
Value of m = + l to - l
Here m = +3 to -3
Value of s = or
