can you tell me when was this first chemical element you just mentioned discovered?
It has the symbol N and atomic number 7.
Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name "nitrogène" was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790 when it was found that nitrogen was present in nitric acid and nitrates. Antoine Lavoisier suggested instead the name "azote", from the Greek ἀζωτικός "no life", as it is an asphyxiant gas; this name is instead used in many languages, such as French, Italian, Russian, Romanian and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds.
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.
