Answer:
(1)
(2) but
transition not allowed.
Explanation:
Atoms can be described by the quantum number n, spin quantum number S, angular momentum quantum number L, and total angular momentum quantum number J. Based on approximation Russel- Saunders electron coupling, the atomic term symbol can be written as .
The conditions or selection rule to promoting the electron are discussed below:
(1) The total spin should not change that is .
(2) The total angular momentum change should be, but
transition not allowed.
