Space-filling molecular models: Nitrogen expansion set

Nitrogen generally forms three bonds with other atoms, but it has a pair of electrons that don't participate in these bonds yet still occupy space. The three bonds and lone pair electrons typically arrange themselves in a tetrahedral structure, however if the lone pair is near a double bond, it repositions itself to contribute to the double bond and the bonded atoms rearrange into a flat triangle without breaking any bonds. This 3D arrangement of nitrogen compounds depends on where the lone pair is located. Nitrogen6 represents the tetrahedral form, while NitrogenSP21 signifies the planar structure. Other forms include double and triple bonded nitrogens, but these are mostly found in rare compounds. Compounds with double-bonded nitrogens are often referred to as diazo or other unusual names, use Nitrogen DB1 for this; the bottom socket represents the double bond, technically this bond doesn't rotate, but it's a complex situation. Nitrogen can form a triple bond with carbon to create nitriles, also known as cyanides (popular among those who enjoy solving murder mysteries {by the way, cyanide doesn't smell like bitter almonds; I learned that the hard way, but I'm alive to tell about it}). Elemental nitrogen in the air is also triple bonded to itself. Use NitrogenTB1 for this. Nitrogen can form four bonds, but this results in a positive charge. To represent this, use the appropriate carbon atoms with their corresponding colors (they're the same size and shape).
