► More about the history and places to find nitrogen.► Next element of the periodic table.
|AmmoniaThis is an ammonia molecule with the formula, NH3. Scientists use the name "ammonia", the same way they call H2O "water". In this compound, three hydrogen (H) atoms share their electrons with the nitrogen (N) atom. This way the nitrogen has a filled outer shell and the hydrogens have two electrons to fill their shells.|

|Nitrogen TrichlorideNitrogen can combine with three chlorine (Cl) atoms, forming nitrogen trichloride, or NCl3. Nitrogen shares its electrons with the chlorine atoms, so all of the atoms have their shells filled.Take a look at the dots around the atoms. All of them now have eight electrons, and a filled outer shell!|
|Cyanogen ChlorideHere"s something new! We have three different elements here, carbon, nitrogen, and chlorine. That"s not special, but the way they combine is! Look at the carbon and the nitrogen, they are sharing six electrons!When two atom share two electrons, that"s a single bond. If they share four it"s a double bond. Well these two are sharing six, that"s a triple bond. It"s extremely strong and powerful. It would take a lot of work to separate the C and the N!One more thing! Because the bond between carbon and nitrogen is so strong, scientists call them "cyanogen" instead of carbon-nitrogen. Scientists know that cyanogen is always CN.|
