It is a chemical element and is naturally gas, symbolized by N, and has seven electrons in its orbits. It is a non-metallic element. It is found in the form of N2 molecules. It has no color, no odor. It is made up of many important compounds such as ammonia , And it is an important component of nucleic acids that carry genes and recipes of different organisms.
Daniel Rutherford discovered the element of nitrogen. Jabir ibn Hayyan was the first to deal with nitrogen compounds such as nitric acid, which he called the water of fire. It was also used in gunpowder, as it was called inert gas or flame retardant. His current name was Antoine Chaptal He was the first to launch it, and the world William Strout expressed it as a bright yellow cloud.
In nature, nitrogen gas is abundant in nature. It is the most abundant gas in the air, accounting for approximately eighty-eight percent of the total air. Its presence in the earth's crust is minimal because its salts dissolve in water and therefore do not form deposits in layers And is ranked as the seventh most common element in the universe. It is one of the starburst fusion products. It accounts for two to six percent of the weight of the plant after drying. It also has an abundance of animal waste in its compounds, urea and uric acid.
In natural conditions, nitrogen is present in the form of gas, has no color, no odor, no taste, and is non-flammable, but can be converted to its liquid state at very low degrees, at about -196 ° C, in this case less dense than water , And can be frozen at temperatures as high as -102 ° C, and become crystals, which is weak in water.
Nitrogen is an element not metal, and there in five atoms of electrons in the last orbit, and thus it carries a negative charge, ie it acquires electrons during the reaction, or shared by, and reacts strongly with alkali metals, transition metals, and compounds:
1-Lithium nitride.
2- Ammonia. Nitrogen chloride.
3- Nitric oxide.
In addition to a large group of organic compounds consisting of proteins in all its forms, whether amino acids simple form, or enzymes made in the body, or bio-cell build proteins, and is used in its liquid form for cooling in chemical laboratories, it is also used in medicine to freeze and remove warts.
