Question

angular orbital momentum of people subshell is
​

Answer 1

A closed subshell is an eigenstate of total orbital angular momentum operator squared, L2, with the quantum number L=0, so that the eigenvalue L(L+1) is also zero.

Answer 2

The d subshell (ℓ = 2) contains five orbitals, with mℓ values of −2, −1, 0, 1, and 2. The spin projection quantum number (ms) describes the spin (intrinsic angular momentum) of the electron within that orbital, and gives the projection of the spin angular momentum S along the specified axis: Sz = ms ħ.
