CHE SIGNIFICA NITROGEN IN INGLESE
Azoto
L'azoto, il simbolo N, è l'elemento chimico del numero atomico sette. A temperatura ambiente, è un gas di molecole diatomee ed è incolore e inodore. L'azoto è un elemento comune nell'universo, stimato a circa settima nell'abbondanza totale della nostra galassia e del sistema solare. Sulla Terra, l'elemento si trova principalmente come la molecola di gas; Forma circa il 78% dell'atmosfera terrestre. L'elemento dell'azoto è stato scoperto come componente separabile dell'aria, dal medico scozzese Daniel Rutherford, nel 1772. Molti composti industriali importanti come ammoniaca, acido nitrico, nitrati organici e cianuri contengono azoto. Il legame estremamente forte in azoto elementare domina la chimica dell'azoto, causando difficoltà sia per organismi che industriali nella conversione del N 2 in composti utili, ma allo stesso tempo provocando il rilascio di grandi quantità di energia spesso utile quando i composti bruciano, esplodono o decadono Indietro nel gas azotato. Gli ammoniaca ei nitrati prodotti sinteticamente sono concimi industriali fondamentali e nitrati di fertilizzanti sono i principali inquinanti nel provocare l'eutrofizzazione dei sistemi idrici.
