Question
An electron is in one of the 3d orbitals. Give the possible values of n, l and ml for this electron.
Solution
For 3d orbital. The principle quantum number is n=3.
(azimuthal quantum number) l = 2.
For the (magnetic quantum number ml) that is given by the rule such as (2(l) +1) = (2 x2 +1) =5. Thus, the possible value of ml = -2, -1, 0, +1 +2.
