1.what is the purpose of each of the five parts of the mass spectrometer?
2.if hydrogen has only one electron,how can it have five lines in its line emission spectra?
3.a）evidence for the existence of energy levels in atoms is provided by line spectra.state how a line spectrum differs from a continuous spectrum
b)on the diagram below draw four lines in the visible line spectrum of hydrogen
c)explain how the formation of lines indicates the presence of energy levels

不一定对，你参考下
1 质谱的五个部分都有什么作用。
2 如果氢只有一个电子，在它的发射谱中为什么有5跟谱线
3 原子能级被谱线理论证明的证据，说明谱线和连续光谱的不同
在以下的图中可见的四根可见氢的谱线，解释如何谱线构成说明现有的能级。
看不懂，帮忙翻译下~~~~~
