Question

Transcribed Image Text:1. Atomic spectroscopy analyses the elemental composition of the sample, essentially giving
data to hypothesize an empirical formula.
True
False
2. Photodiode arrays are devices within the instrument that help amplify the signal of a
sample.
True
False
3. Atomic spectroscopy requires the atomization of a sample, which involves nebulization and
eventually volatilization to form an elemental vapor.
True
False
4. Organic compounds are normally analysed in atomic spectroscopy despite their small
electronic transition range.
True
False
5. The Beer-Lambert law can be used in atomic spectroscopy to determine the concentration
of an unknown sample based on the reported absorbance.
True
False
6. The camera on a mobile phone can be used as a detector for AAS because it can capture
wavelengths outside of visible light.
True
False
7. Elemental analysis of a sample through atomic spectroscopy reports single bands without
overtones because each element has a unique electronic transition wavelength.
True
False
8. Atomic spectroscopy can detect both absorption and emission radiation as electrons move
from HOMO to LUMO.
True
False

Transcribed Image Text:9. The flame present in atomic spectroscopy allows the atom to reach its highest energy state
because of the radiation present.
True
False
10. In comparing the source of electromagnetic radiation, AES uses a flame or plasma source
while AAS uses a hollow cathode lamp source.
True
False
