Which set is correct for an electron in `4f -orbitial` ?

Options

A. `n = 3 l = 1` m_1 = -2 m_s = + .^1//_2`
B. `n = 4 l = 4 m_l = -4 m_s = - .^1//_2`
C. `n = 4 l = 3 m_l = + 1 m_s = + .^1//_2`
D. `n = 4 l = 3 m_l = + 4 m_s = + .^1//_2`

Answer

C

Explanation

( c) For `4f` orbital `n = 4, 1 = 3`
For `1 = 3, m ne 4`.
