Another word for atomic spectroscopy is elemental analysis. Let’s look at hydrogen as an example. In fact, one of the central results of quantum mechanics is that electrons do not have a definite position (until they are measured), only a definite energy. type: "html5", You may need to download version 2.0 now from the Chrome Web Store.
