Normally, the atoms are in the ground state and the extra-nuclear electrons move in their respective lowest energy orbitals. If a certain external energy, such as light energy, is supplied to the ground state atom, when the external light energy E is exactly equal to the energy level difference _△ E between the ground state and a certain higher energy level in the ground state atom, the atom will absorb light of this characteristic wavelength, and the outer electrons transit from the ground state to the corresponding excited state, forming an atomic absorption spectrum. Electrons are in an excited state after they transition to a higher energy level, but the excited state electrons are unstable, and after a short period of time, the excited state electrons return to the ground state or other lower energy level and release the energy absorbed by the electrons as light, which process forms an atomic emission spectrum. The spectral energy and wavelength emitted by different elements are different, namely characteristic spectral lines, so that the energy or wavelength measurement of the spectral energy or wavelength can be used for knowing what element is emitted, and qualitative analysis of the element is performed. The line strength is related to the content of the element in the sample, so that the quantitative analysis of the element can be performed by measuring the strength of the element.
