Nitrogen+2

**Nitrogen** Element Symbol: N

// (Above is a picture of nitrogen in a liquid form, the vapors show the liquefied nitrogen heating up again and turning back into its natural gas form // **  Chemical characteristics of nitrogen:   **Nitrogen is very common gas that is in the air we breath everyday. It is inert and makes up and entire 78.09% of the air. As previously said nitrogen is an inter gas. Along with that it does not posses any taste, color, or even a smell. Because of this nitrogen goes unnoticed in most day to day activities. **Where is nitrogen found in nature?** Nitrogen can be found in large quantities in the air/atmosphere, but it is also hidden in many other places. The nitrogen cycles help circulate the nitrogen that has been absorbed in to the ground get back into the air. There is a process for the recovery of nitrogen from anaerobically digested liquid waste and for the collection of the nitrogen as nitrate compound.This strips ammonia from anaerobically digested liquid waste, and converts the ammonia into nitrates via nitrification. The stripping gas is heated to improve nitrogen recovery. Nitrogen is a very useful element and is used in many common items. If you have ever had a wart, you might have used nitrogen in its liquid form. When nitrogen is in a liquid form it is extremely cold (−196 °C; −321 °F) and so when applied to a wart, it is frozen off. Nitrogen is also in light bulbs. Light bulbs are filled with nitrogen so that the filaments that create light in the bulbs don't burn (if it was oxygen it would burn) and break, rendering the light bulb useless. On its more destructive side nitrogen is used in an array of highly explosive materials, such as nitroglycerin, nitrocellulose, and trinitrotoluene (aka TNT!!). Lastly on a happier note, nitrogen is also used in laughing gas, a fairly common anesthetic. Nitrogen is an inert gas. Therefore there are no health risks associated with it whilst it is in its pure form. However if you stuck you hand in a container of liquid nitrogen, you would not be getting it back because of the extremely low temperature of liquid nitrogen. As far as toxicity thought, nitrogen poses no threat. Disposing of nitrogen is simple, it does it on its own, whether is through simple evaporation(from its liquid state) or through one of the nitrogen cycles; nitrogen will almost always find its way back into the atmosphere. While nitrogen obtains no real nutritional value to humans or animal directly, it indirectly affects our nutritional need. This is because nitrogen is extremely beneficial to plants and is used in fertilizer. We may not need it in our diets, but the plants that we **//do//** need and eat require it.
