Operating elements

CHEMnet has different operating elements: You can find a page navigation (orange) as well as a comprehensive navigation (blue).

Apart from the page on the screen, the orange page navigation on the left side indicates the previous and the following pages as well. With the orange page navigation at the top you can move to a higher level: If you find yourself, e.g., on a subordinate page you will get to the main chapter again.
The blue navigation on the left contains a listing of the chapters, a whole text search as well as an index where you can look directly for terms in alphabetical order. With the logout button you can log off or get to the exercises. This is optional because your session has finished when you leave your browser. In the upper part of the site in the blue main navigation you find the following domains: table of contents, E-mail for professional and technical questions, exercises, help (plugins, periodic table of elements, constants, Greek alphabet) as well as the printing function making possible the printing of technical texts without any further frames.


The CHEMnet text contains a lot of pictograms leading to additional contents. The different pictograms are explained in the following table. In the screen shot above if you click on the small on this page of the lecture (not in the operating instructions, of course), you will get further information about the underlined term.
