Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
This biological process is a redox comproportionation reaction, in which ammonia (the reducing agent giving electrons) and nitrite (the oxidizing agent accepting electrons) transfer three electrons and are converted into one molecule of diatomic nitrogen (N. 2) gas and two water molecules.
Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds: Charge-neutral. Nitric oxide (NO), nitrogen (II) oxide, or nitrogen monoxide. Nitrogen dioxide (NO2), nitrogen (IV) oxide. Nitrogen trioxide (NO3), or nitrate radical. Nitrous oxide (N2O), nitrogen (0,II) oxide.
Liquid nitrogen (LN2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air.
El cuerpo humano contiene alrededor de un 3% de nitrógeno en masa, el cuarto elemento más abundante en el cuerpo después del oxígeno, el carbono y el hidrógeno. El ciclo del nitrógeno describe el movimiento del elemento desde el aire, hacia la biosfera y los compuestos orgánicos, y luego de vuelta a la atmósfera.
Nitrogen dioxide is a chemical compound with the formula NO 2.One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas.It is a paramagnetic, bent molecule with C 2v point group symmetry.Industrially, NO 2 is an intermediate in the synthesis of nitric acid, millions of tons of which are produced each year, primarily for the production of fertilizers.
