where is this element can be found?
From nitre (potassium nitrate, saltpetre) and sodanitre (sodium nitrate, Chilean saltpetre).
Nitrogen
The only important nitrogen minerals are nitre (potassium nitrate, saltpetre) and sodanitre (sodium nitrate, Chilean saltpetre).
how are saturn's moon titan and neptune's triton similar Both of them are geologically active. who discovered the triton? William Lassell. when was it discovered? 10 October,1846. can you mention some physical characteristics of this natural satellite? Triton's crust consists of 55% nitrogen ice with other ices mixed in. Water ice comprises 15–35% and frozen carbon dioxide the remaining 10–20%. Its surface area is 23 million km. how is the atmosphere there? It has a tenuous nitrogen atmosphere, with trace amounts of carbon monoxide and small amounts of methane near its surface. can you tell me when was this first chemical element you just mentioned discovered? It has the symbol N and atomic number 7.

Nitrogen [SEP] Occurrence
Nitrogen is the most common pure element in the earth, making up 78.1% of the entire volume of the atmosphere. Despite this, it is not very abundant in Earth's crust, making up only 19 parts per million of this, on par with niobium, gallium, and lithium. The only important nitrogen minerals are nitre (potassium nitrate, saltpetre) and sodanitre (sodium nitrate, Chilean saltpetre). However, these have not been an important source of nitrates since the 1920s, when the industrial synthesis of ammonia and nitric acid became common. Nitrogen compounds constantly interchange between the atmosphere and living organisms. Nitrogen must first be processed, or "fixed", into a plant-usable form, usually ammonia.
