What kinds of transitions form the basis for AA and AE?
Can the detector differentiate wavelengths of light?
What kind of stable compounds are produced from aqueous aluminum in an air-acetylene flame?
Which is hotter, an air-acetylene or nitrous oxide-acetylene flame?
What colour is calcium emission?
Atomic absorption measures the transistions occuring when an atom is excited to higher electronic levels by absorption of energy from a sources(example flame).
Atomic emmision measures the transistions when an atom in excited electronic state loses energy to come back to ground state electronic level.

Find on-line a Grotrian diagram for the sodium atom. What wavelengths (in nm) are the most sensitive for the analysis of Na atoms in an atomic absorption experiment? What energy levels are involved in these electronic transitions? Na can also be measured by the process of atomic emission, where the heat from the flame is used to excite the atom to its excited state. What fraction of Na atoms are excited in an acetylene-air flame at a temperature of 2200C?...
What kind of stable compounds are produced from aqueous aluminium in an air-acetylene flame? This relates to atomic absorption spectroscopy. Any help would be greatly appreciated!
