Question
(i) An atomic orbital has n = 3. what are the possible values of l and ml ?
(ii) List the quantum number (ml and l) of electrons for 3d orbital.
(iii) Which of the following orbitals are possible: 1p, 2s, 2p, and 3f?
Solution
(i) For n = 3; l = 0, 1 and 2
For l = 0, ml = 0
For l =1, ml = -1, 0+1
For l = 2, ml = -2, -1, 0, +1, +2
(ii) For 3d orbital, n = 3, l =2
For l =2, ml = -2, -1, 0, +1, +2
(iii) 1 p is not possible because when n = 1, l = 0 only (For p, l = 1)
2s is possible because when n =2, l = 0, 1(For s, l = 0)
2p is possible because when n=2, l = 0, (For p, l = 1)
3f is not possible because when n = 3, l = 0, 1, 2(For f, l = 3).
