Principal quantum number n n = 1, 2, 3, …

Azimuthal quantum number (angular momentum) ℓ for n = 3: ℓ = 0, 1, 2 (s, p, d)

Magnetic quantum number (projection of angular momentum) mℓ for ℓ = 2: mℓ = −2, −1, 0, 1, 2

Spin quantum number ms for an electron s = 12, so ms = − 12, + 12

Answer:

whom no

i think pretty or chandni or other else

Explanation:

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms).
