WebNitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas.Nitrogen is obtained from liquefied air through a process known as fractional distillation. Web20 de jul. de 2024 · 81. The short answer is that (i) protons (hydrogen nuclei) are produced abundantly in the early universe, but only a small fraction of these are able to engage in nuclear reactions leading to heavier elements, either during primordial nucleosynthesis or later inside stars. This means that hydrogen ends up being the most abundant element … high grade bowel obstruction definition
