An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge. Ions are crucial in the formation of spectral lines when atoms interact with radiation.
5 Must Know Facts For Your Next Test
Ions are created when atoms gain or lose electrons due to high energy interactions.
The presence of ions can alter the spectral lines emitted by a substance.
Ionization levels can indicate the temperature and density of astronomical objects like stars and nebulae.
Different elements ionize at different energy levels, affecting their spectral characteristics.
Spectral lines from ions provide information about the chemical composition and physical conditions of celestial bodies.
