JEE MAIN - Chemistry (2004 - No. 55)
Which of the following sets of quantum numbers is correct for an electron in 4f orbital?
n = 4, l = 3, m = +1, s = + 1/2
n = 4, l = 4, m = -4, s = - 1/2
n = 4, l = 3, m = +4, s = + 1/2
n = 3, l = 2, m = -2, s = + 1/2
Paliwanag
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 = $$ + {1 \over 2}$$ or $$ - {1 \over 2}$$
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 = $$ + {1 \over 2}$$ or $$ - {1 \over 2}$$
