A. n = 1, l = 0, ml = 0
B. n = 2, l = 0, ml = 0
C. n = 2, l = 1, ml = 1
D. n = 3, l = 2, ml = 1
E. n = 3, l = 2, ml = 0
Choose the correct answer from the options given below:
In multielectron atoms, orbital energy depends on n and l only, not on ml (in absence of external fields).
A → 1s orbital
B → 2s orbital
C → 2p orbital
D → 3d orbital (ml = 1)
E → 3d orbital (ml = 0)
Orbitals having same n and l but different ml have same energy.
D and E both represent 3d orbitals (n = 3, l = 2) with different ml values.
Correct Answer = D and E Only
