Question

Which of the following combinations of quantum numbers are allowed for an electron in a one-electron atom? n=1,1=0.m=0,m, =- n=1,1=1,m=-1, m, = + n=7,1=3, m= 4, m, = +% n=3,1=1,m=0,m, = 4 Submit Answer 3 question attempts remaining

Answer 1

for option 1:
This is valid

for option 2:
l must be less than n
Here value of n is 1
But value of l is 1
so, l can't be 1
Hence, this is not valid

for option 3:
Value of l is 3
So, valid values of ml are [-3, -2, -1, 0, 1, 2, 3]
so, ml can't be 4
Hence, this is not valid

for option 4:
This is valid
Answer: option 1 and 4
