I understand that when a particular atom is shone by white light, some corresponding spectra of white light will be absorbed by the atom to excite its electrons.
My question is, when an atom has its electrons excited, does it "naturally" tend to bring back its electrons to the ground state (or lower state) and emits photons along the way, or do we have to "trigger" the movement? (the atom tends to conserve its electrons in excitement)
Thank you!
