Match the type of atomic spectroscopy with its description. a. Atoms are thermally promoted to the excited state through collisions in the plasma. As they return to a lower energy state, they emit photons. No excitation source outside of the plasma is required.
b. The sample is atomized in the flame. A laser is used to promote the atoms in the flame to an excited state. As the atoms return to the ground state, they fluoresce.
c. The atomized sample in the flame absorbs a portion of the radiation emitted from the source, which is composed of the same element as that which is being analyzed. The amount of radiation that passes through the flame unabsorbed by the analyte is measured.
i. atomic fluorescence
ii. atomic emission
iii. atomic absorption
