Question

List the quantum numbers (l and $m_{l}$) of electrons for 3d– orbital.

Answer 1

The “electrons” are present in 3d- orbital as given in the question.

For the 3d orbital, we know that the

• “Principal quantum number = 3, i.e., n = 3”
• “Azimuthal quantum number = 2, i.e., l = 2”
• When “Azimuthal quantum number  l = 2 then the value of ml = -2,-1, 0 ,+1,+2”
• And the “Magnetic quantum number = – 2, – 1, 0, 1, 2” i.e., ml = – 2, – 1, 0, 1, 2.  

Answer 2

Answer:

For an electron in 3d orbital, the possible values of the quantum numbers are n=3, l=2, ml=−2,−1,0,+1,+2
