Edit this paragraph the reasons for the color reaction of flame When the alkali metal and its salts in the ignition flame, the atoms absorb the energy of the electron from the orbit of low-energy transition to a higher energy orbit, but at a higher energy orbit is unstable electronic, it is fast transition back to a lower energy orbit, then the energy will be redundant form to emit light.

编辑本段焰色反应的原因当碱金属及其盐在火焰上灼烧时，原子中的电子吸收了能量，从能量较低的轨道跃迁到能量较高的轨道，但处于能量较高轨道上的电子是不稳定的，很快跃迁回能量较低的轨道，这时就将多余的能量以光的形式放出。

However, due to the structure of alkali metal atoms in different electronic transition energy when the change is not the same as on the different wavelengths of light, the color reaction from the flame in the experiment see the special flame color, the color spectrum is the spectrum.

但由于碱金属的原子结构不同，电子跃迁时能量的变化就不相同，就发出不同波长的光，，从焰色反应的实验里所看到的特殊焰色，就是光谱谱线的颜色。
