Fig. Atomic theory began with John Dalton (Figure \(\PageIndex{6}\)) in the 18 th century when he proposed the concept of atoms, that all atoms of an element are identical, and that atoms of different elements can combine to form molecules. A third field in atomic spectroscopy is atomic fluorescence. INTRODUCTION: Atomic Absorption Spectroscopy is a very common technique for detecting metals and metalloids in samples. Another feature of the atomic absorption spectrum in Figure 10.20 is the narrow width of the absorption lines, which is a consequence of the fixed difference in energy between the ground and excited states. The process of atomic absorption spectroscopy (AAS) involves two steps: 1. The key difference between atomic absorption and atomic emission is that atomic absorption describes how atoms absorb certain wavelengths from the electromagnetic radiation whereas atomic emission describes how atoms emit certain wavelengths.. Absorption and emission of an atom help to identify atoms and provide many details about them.
