#### Question

An electron is in one of the 3d orbitals. Give the possible values of *n*, *l* and *m*_{l} for this electron.

#### Solution

For the 3d orbital:

Principal quantum number (n) = 3

Azimuthal quantum number (l) = 2

Magnetic quantum number (m_{l}) = – 2, – 1, 0, 1, 2

Is there an error in this question or solution?
