Nitrogen (N), nonmetallic element of Group 15 [Va] of the periodic table. Liquid nitrogen resembles water in its appearance, as it is colorless. At about the same time, nitrogen also was recognized by a Scottish botanist, Daniel Rutherford (who was the first to publish his findings), by the British chemist Henry Cavendish, and by the British clergyman and scientist Joseph Priestley, who, with Scheele, is given credit for the discovery of oxygen. One way to prepare nitrogen gas is by liquefaction and fractional distillation from the atmosphere. It exists as a colorless, odorless, nontoxic gas and makes up about 78 percent of the atmosphere. Nitrogen - The Element. The atmosphere also contains varying small amounts of ammonia and ammonium salts, as well as nitrogen oxides and nitric acid (the latter substances being formed in electrical storms and in the internal combustion engine). Liquid nitrogen boils at 77 K (−196 °C, −321 °F). 8. Free nitrogen is found in many meteorites; in gases of volcanoes, mines, and some mineral springs; in the Sun; and in some stars and nebulae.

Grant Thompson, who is also known as The King of Random,conducted an fascinating experiment during which he tried to add food color to liquid nitrogen.The results were mixed; while the nitrogen didn’t change color, the dye froze into neat little beads. Even though there is a large amount of nitrogen in the air, there is very minute in the Earth's crust. What are these rare chemistry ingredients? Nitrogen atoms have seven electrons and 7 protons with five electrons in the outer shell. Updates? Oxidizing gas cylinders are light blue in color and inert gas cylinders are bright green. Ring in the new year with a Britannica Membership. Uses of Carbon.
