Stylised atom. Blue dots are electrons, red dots are protons and black dots are neutrons. Date: 14 February 2007: Source: Own work based on: of Image:Stylised Lithium Atom.png by Halfdan.

English: Diagram of an idealized Lithium atom, primarily useful to illustrate the nucleus of an atom. This sort of design is scientifically inaccurate in many important respects, but serves as a powerful mandala of the nuclear age. Inspired by drawing from User:Fastfission, recreated by User:AG Caesar in vector/svg format.
Draw the structure, and save it as a ChemDraw file. If you drew the structure before applying any settings, then you need to select the object, open the "Object" menu and choose "Apply document settings from → ACS Document 1996". Then save it as a PNG file, to be read by an image editor such as GIMP or IrfanView (see below for details).

The nitrogen atom has only 6 electrons assigned to it. One of the lone pairs on an oxygen atom must form a double bond, but either atom will work equally well. Therefore, there is a resonance structure. Tie up loose ends. Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom.
This gives the atom a shell structure designed by Kossel, Langmuir, and Bury, in which each shell corresponds to a Bohr orbit. This model is even more approximate than the model of hydrogen, because it treats the electrons in each shell as non-interacting. But the repulsions of electrons are taken into account somewhat by the phenomenon of ...
A given atom would have solid and hollow valence spikes. The solid rods clicked into the tubes forming a bond, usually with free rotation. These were and are very widely used in organic chemistry departments and were made so accurately that interatomic measurements could be made by ruler.
