焰色反應是一種非常古老的定性分析法，當金屬化合物於火焰中燃燒時，火焰的熱能使得氣化的原子內部電子吸收足夠的能量，躍遷到激發態(excited state)，當電子恢復到基態(ground state)時，會發出特定的光譜線。不同的原子往往會產生不同波長的光譜(發射光譜)。而放出的光的波長在可見光範圍內(波長約為 390nm～770nm)。

結果 (英文) 1:

The flame reaction is a very old qualitative analysis, when the metal compound combustion in the flame, the heat of the flame so that the atomic internal electron gasified absorb enough energy to an excited state (excited state), when the electron returns to the ground state when (ground state), will issue a specific spectral lines. Different atoms tend to produce different wavelengths of the spectrum (emission spectrum). And the wavelength of light emitted in the visible range (wavelength of about 390nm ~ 770nm).

結果 (英文) 2:

Flame-color reaction is a very old qualitative analysis, when a metal compound burns in a flame, the thermal energy of the flame causes the gased-natured internal electrons to absorb enough energy to jump to the excitation state, and when the electrons recover to the base state, they emit specific spectral lines. Different atoms tend to produce spectra (emission spectra) at different wavelengths. The wavelength of the emitted light is within the visible light range (wavelengths are about 390nm to 770nm).

Flame reaction is a very old qualitative analysis method. When the metal compound is burned in the flame, the heat energy of the flame makes the electrons inside the vaporized atom absorb enough energy and jump to the excited state. When the electrons return to the ground state, they will emit specific spectral lines. Different atoms often produce different wavelengths of spectrum (emission spectrum). The wavelength of the emitted light is in the range of visible light (the wavelength is about 390nm ~ 770nm).
