Are u talking about electron sublevel config or where the electrons show in the "rings" of the atom
The answer is number 1 - energy is emitted
Energy is released when an atom in an excited state returns to the ground state.
PH + pOH = 14
12.52 + pOH = 14
pOH = 14 - 12.52
pOH = 1.48
[OH⁻] = 10^ -pOH
[OH⁻] = 10 ^- 1.48
[OH⁻] = 0.033 M
