Question

According to the provided text, what is the principle used in Atomic Absorption Spectroscopy?
Options
A Excited atoms emit light when returning to a lower energy state.
B Atoms spontaneously re-emit absorbed radiation as fluorescence.
C Free electrons generated in an atomizer absorb radiation at a specific frequency corresponding to electronic transitions.
Correct Answer
D The measurement of emitted light from a heated metal chloride sample.
Correct Answer

Option C is the correct answer.

Detailed Explanation

As stated on page 7, "Atomic absorption spectroscopy: ...The atomic absorption spectroscopy principle uses the fact that the free electrons generated in an atomizer can absorb radiation at a specific frequency corresponding to electronic transitions. It quantifies the absorption of ground-state atoms in the gaseous state."

Hint

'Absorption' implies taking in energy. How is this energy taken in by atoms in this technique?
