Question

Give the values of a quantum no.For the electronin 5f orbitals what will be the possible values for magnetic quantum no.For highest energy electron.

Answer 1

The principal quantum number, or n, describes the energy lelvel in which the electron can be found, Since you're interested in an electron located in a 5d-orbital, n=5.

The angular momentum quantum number, or l, describes the subshell, or orbital type, in which your electron is located. Since you have a d-orbital, l=2.

The value of l will give you the value of the magnetic quantum number, or ml, which describes the orientation of the orbital.

The accepted values for ml range from −l to +l, which means that you can have 5 d-orbitals in the fifth energy level, dxy, dxz, dyz, dz2, and dx2−y2, each described by a magnetic quantum number

ml=−2 

ml=−1 

ml=0 

ml=+1 

ml=+2

As an example, here's how these orbitals would look for the 3d subshell
