Question

4. For principle quantum number (n) 5, list all the possible values of the angular quantum number (), and for each value of 7, list all the values of the magnetic quantum number (mi)

Answer 1

Rule: for given n, l can take all values from 0 to n-1

Rule: for given l, ml can take all values from -l to +l

For n=5,
l can be 0, 1, 2, 3, 4

for l = 0, ml = 0
for l = 1, ml = -1, 0, 1
for l = 2, ml = -2, -1, 0, 1, 2
for l = 3, ml = -3, -2, -1, 0, 1, 2, 3
for l = 4, ml = -4, -3, -2, -1, 0, 1, 2, 3, 4
