How are atomic emission spectra used to identify elements?
As the atom emits photons at precise frequencies it creates a similar
atomic emission spectra to other atoms within its group.
Atoms absorb photons and emit energy at definitive frequencies creating a
universal atomic emission spectra common to all atoms.
When the atom absorbs photons, energy can only be emitted at specific
frequencies creating a characteristic atomic emission spectra.
The atom absorbs photons and emits a continuous spectrum of energy but
only certain frequencies can be detected creating the spectra.
